AUTO TUNERS (A Division of GIRIRAJ Electronics) Car Tuning service can come direct to your door within our service area – that could be your home, office or any other location which is suitable to you. We do not charge you extra to serve you at your doorstep. After receiving your order, we will contact you within 24 hours (Monday to Friday) to arrange a mutually convenient time to meet and tune your vehicle. But if your car is required to take our workshop in that case we may need your vehicle for 1 day to 1 week depends upon your vehicle.

We guarantee higher torque early in the rev range for improved pulling and climbing power. Our Tuning is becoming an increasingly popular service for individuals who travel with high load since it improves the car’s towing power in general. Tuning for high torque vehicles can drastically help in providing that extra torque at lower rev ranges which is needed for faster and safer overtaking. What’s more, a tuning will not increase your emissions in any way.

Our pricing is directly proportion to the amount of work that we need to undertake to tune your Car, and this differs for each car model. We Request you to please call us or mail us directly for pricing.

Our Tuning service will benefit both Petrol & Diesel Engines. However, Turbo Diesel Injection models (TDI) will show the greatest results from a performance & Economy point of view.

The process to get your vehicle tuned is as under.

Step-1. Fill-up all the field of Contact us form & submit.

Step-2. After receiving your mail we reply you with one more from in which we need further more details of your vehicle which we need to tune your vehicle.

Step-3. Once we received the Customer submission from filled from you, we give you our Quot. For your vehicle & also provide you the details of Tuning time we need to do the job. (If we want to check the compatibility we visit at your location to check the same within our service location)

Step-4. After confirmation mail received from you we provide you the Date & time so, you can plan your schedule. If the date & time provided by us is not suitable to you, pl. Provide us your most suitable date & time.

Step-5. After we both fix the date & time you have to deposit the amount in our bank account. (ONLY BY CHEQUE OR NET BANKING. NEVER DEPOSIT THE AMOUNT BY CASH AS WELL AS WE DO NOT RECEIVE THE PAYMENT IN CASH.) Once we received your payment in our Bank account within 24Hrs. our representative will call you.

Step-6. On the scheduled date we visit your location or you have to visit at our workshop & in your presence we do the test.     

Our Engineer check your vehicles parameters, if your vehicle is compatible our engineer give you confirmation & conduct a test in your presence. After your confirmation we Tune your vehicle and you then have opportunity for yourself to experience the amazing results. Depending on the vehicle, the tuning time normally we take from 1 hour to 1 week to complete the job.

Our Tuning process enhances and optimises the power of the engine within safe limits, not beyond them. Extra power will also result in fewer gear changes, which might actually reduce overall wear & tear. Manufacturers have to build in a tolerance for the parts in the engine, to manage the effect of wear and tear, production variations, and to ensure their warranty claims during their warranty period normally 3 years, are kept to a minimum.

Most race and rally engines are pushed for every last bhp, and thus they more common to fail, whilst normal car/van/lorry engines are limited back, well away from probability of multiple failures. Each individual engine is different as in how much it can be pushed in a tuning, but a good tuning from a quality tuner like Auto Tuners will never get close the limits of component failure.

You will see that the top companies within the market place have all develop vehicle improvements to similar outputs. Beware of tuners who claim significantly more, it’s either lies hoping that the average customer wouldn’t be able to tell the difference.

Manufacturers generally sell one vehicle that covers various markets, with different tax and emissions regulations, different climates with extremes of heat, cold, humidity, different fuel quantities, different operating altitudes, etc. A manufacturer has to take all of these factors into consideration and make substantial compromises in the vehicles operation. We optimise the engine tuning and outputs as per conditions of your driving & requirement.

Every vehicle tuned by AUTO TUNERS is guaranteed to ensure your complete peace of mind and continued service.

If the installation becomes faulty, we will re-install it free of charge at our workshop. A professionally tuned engine will not cause technical faults with a well serviced and maintained the engine.

If you want to tune your diesel vehicle and still keep the vehicles safety and durability functions for the engine/transmission/ESP intact, the only way to tune a diesel vehicle is to make changes in the existing control system of the engine. That is exactly what we offer at AUTO TUNERS. Our tuning process has total control over all parameters at any moment, and we don’t disturb the safety functions of the car, by deceiving the system.

Apart from an obvious power, torque and fuel economy benefits you get the following advantages with an AUTO TUNERS Tuning Service:
• The Tuning process is completed within 1 Hour to 1 Week depends upon the Vehicle.
• Nothing needs to be connected to the vehicle after tuning to get the benefits.
• No loose boxes and wiring flexes in the engine compartment.
• Torque comes soft and smooth.
• Torque is adjusted/limited on lower gears (to avoid damage on the transmission)
• Boost pressure and air flow is optimised.
• The original settings can be done easily if required.
• On board computer shows correct fuel consumption.
• Anti-skid program (ESP) function is fully retained.
• Torque reduction when shifting gear (for comfort and durability) is retained.
• Regeneration (emptying) of diesel particle filter (DPF) is retained optimal.
• Correct calculation of exhaust temperature.
• Correct calculation of service interval.
• The diagnostic system is retained.
• No enlarged NOx, HC, CO, CO2, Soot emissions compared with original when going for MOT and servicing.

We are very confident that your AUTO TUNERS tuning process will both improve your driving experience and save you substantially on fuel. But, don’t take our word for it, try the upgrade for 15 days and if you are not satisfied with the results, we retuned your vehicle till your satisfaction or refund the amount after deducting some process charges.

We advise that it is your responsibility to inform your insurance Company for any modification to your vehicle. We are finding that more and more insurance companies are not penalising their customers for saving fuel and recognise our economy upgrades, in particular with AUTO TUNNERS. We can provide a certificate of conformity if required.

Yes, in secure server storage, if you ever require your vehicle to put back to original tuning we can do the same because we have the complete parameters of your vehicle along with your personal contact information.

Some manufactures diagnostic equipment may detect a tuning. Additionally many forward thinking manufacturers turn a blind eye to a quality tuning service, knowing that a properly enhanced vehicle can only ever benefit them. The official line from most manufacturers is that if a modification causes a problem with the vehicle, then the part of the vehicle affected will not be covered under warranty, this does not mean a independent cancelling of the whole warranty.

A full AUTO TUNERS Engine tuning alters the fuel, boost and torque characteristics of the engine. By controlling the fuel pressure, injected fuel quantity, maximum permissible visible smoke limit, boost pressure from the turbocharger and the torque characteristic.
We at AUTO TUNERS offers a fully controllable change to the engine characteristics, whilst still operating with full engine feedback control and within all the pre-set engine sensor limits.

We do not fit add-on tuning boxes, which normally just interfere with engine management signals to trick the injectors into adding more or less fuel. Our service is a custom tuning done specifically for your vehicle.
These differ from how a tuning works. A tuning box relies on the principal of more diesel fuel = more diesel power. That theory is correct and boxes do increase power, but they can’t control the amount of black smoke (maximum permissible visible smoke limit) coming out the exhaust.
Too much smoke is undesirable, both environmentally and visually. More importantly, the black smoke is un-burnt diesel fuel attached to combustion chamber, with deposits exiting straight out the exhaust pipe, thus wasting fuel which hasn’t had any effect on power gain. The results are raised emissions, a higher thermal load on the engine (i.e. exhaust temperature) and frequently defects such as "bucking" are often the result. It should be clear what this means for your engine.
In a modern engine there are complex engine control systems that cooperate with each other to make everything work perfectly. A diesel box manipulates some signals in order to either increase the injection time or fuel pressure. Unfortunately this manipulation is done entirely without the engine control system’s knowledge. This means that a diesel box tricks the engine control system of the vehicle and the consequence is that a large amount of values and control data will be incorrect, resulting in:

• The on board trip computer shows improved fuel consumption, but the real amount left in the tank is less, as fuel is being injected without any of the sensors detecting the additional amount entering the cylinder.
• The anti skid program (ESP) is disturbed because of incorrect torque value.
• Loose boxes and wiring flexes in the engine compartment.
• The automatic gearboxes get incorrect torque value.
• Torque reduction when shifting gear (for comfort and durability) is not retained.
• The regeneration (emptying) of particle filter will not be optimal.
• The calculation of exhaust temperature is disturbed.
• The calculation of service interval is disturbed.
• The diagnostic system is disturbed.

Torque is the twisting force created in an engine by rotating parts; horsepower is the measurement of how fast torque is being used. Horsepower and torque work hand-in-hand, as horsepower is calculated from torque.
For the average buyer, torque shouldn’t be a deciding factor unless you know you’ll be towing or hauling heavy loads. And that’s where high-torque vehicles will do well, driving while towing a trailer or maxing out cargo capacity. It will be easier to accelerate and sustain speed with a high-torque car in any situation, but especially with heavy loads.
High performance cars can also produce lots of torque that greatly aid in acceleration. That feeling of your eyeballs being sucked into the back of your head in a fast car during heavy right-foot pounding is an example of excessive torque.

Brake horsepower (BHP) is the measure of an engine's horsepower before the loss in power caused by the gearbox, alternator, differential, water pump, and other auxiliary components such as power steering pump, muffled exhaust system, etc. Brake refers to a device which was used to load an engine and hold it at a desired rotational speed. During testing, the output torque and rotational speed were measured to determine the brake horsepower. Horsepower was originally measured and calculated by use of the "indicator" (a James Watt invention of the late 18th century), and later by means of a De Prony brake connected to the engine's output shaft.
More recently, an engine dynamometer is used instead of a De Prony brake. Although the output delivered to the driving wheels is less than that obtainable at the engine's crankshaft, a chassis dynamometer gives an indication of an engine's "real world" horsepower after losses in the drive train and gearbox. This gives a reasonably accurate indication of how a wheeled vehicle engine will perform once on the road.

A newton metre is a unit of torque (also called "moment") in the SI system. The symbolic form is Nm or N•m. One newton metre, sometimes hyphenated newton-metre, is equal to the torque resulting from a force of one newton applied perpendicularly to a moment arm which is one metre long.
It is also used less commonly as a unit of work, or energy, in which case it is equivalent to the more common and standard SI unit of energy, the joule. In this very different usage the metre term represents the distance travelled or displacement in the direction of the force, and not the perpendicular distance from a fulcrum as it does when used to express torque. This usage is discouraged by the SI authority, since it can lead to confusion as to whether a given quantity expressed in newton-meters is a torque or a quantity of energy.

Forced induction i.e. Turbo charging or Supercharging allows a tuner to fine tune and control the amount of air your engine needs to consume at all times. Naturally aspirated engines will benefit from our Tuning service, but due to lack of forced induction, your engine will see gains up to 10%.

Not at all. Your emissions will not be affected in any way due to our clean burn approach. In Diesels, even with the manufacturer’s original tune, a small amount of smoke under wide open throttle is normal, and this usually subsidies into a haze as you accelerate. Thanks to our strict rule of clean burn, we ensure that your car doesn’t unnecessarily smoke any more than what it did before you tuned your car with us.
