Why TunerWerks?

We do understand there are a number of tuning providers to choose from, and from a website many look the same. We would seek to assure you that TunerWerks is not just another tuning provider. Our tuning services have been developed in-house over the last 20+ years and are some of the very best tunes available in the world today. TunerWerks is the one of the only ISO certified tuning and training provider. We are approved and used by the largest fleet and industry professionals across the world. All tuning is insured and comes with our money back guarantee. If your tuner can't demonstrate how they develop and test their tuning and that they conduct dyno and emissions testing (a legal requirement) - don't you just wonder how they do it? TunerWerks ECU tuning & remapping is dyno developed and emission tested.

 

Why have I not heard of TunerWerks?

TunerWerks has been tuning cars since 1995 for motorsport teams around the world and was not available to the retail public. From there we opened up our ECU tuning services and were contracted out by some of the more popular European tuners.

 

So why don't manufactures tune their vehicles?

The most common of all tuning questions, it is not complicated, but there are a few answers to this question, some more obvious than others. Vehicle manufactures are in a tough position here, they have to build one vehicle for all drivers, it's a bit like a nice suit off the shelf, it fits well, its looks smart, but it can't be custom tailored for the end customer, tuning is just the same, if you own a fleet of vans you may want a speed limiter or rev limiter added to help save your fuel, yet another customer may want a little more power to help with towing, or heavy payloads, these sort of changes can only be made once the vehicle is built and the customer needs something other than off the shelf fuel quality, we are often asked to tune for different fuel quality, either higher or lower, once an owner knows where his vehicle will be used and what it will be used for, we can adapt the tuning for environmental, altitude and fuel quality.

 

Will ECU tuning void my warranty?

Technically, no. A remap or any aftermarket work cannot and will not automatically invalidate a vehicle's warranty. However, we go through rigorous testing regime for all ECU remapping and vehicle tuning files. That being said, certain dealership or service advisor may still void the warranty. It's like getting correction ticket even though you have 50-state legal exhaust system. If you are still concerned about voiding factory warranty, then we have tuning modules available for most late models.

 

Will the life of my engine be reduced?

No, not at all if you use TunerWerks. Sadly some engines can be over-tuned, "stressing" the engine, transmission, cooling systems, brakes, etc, and reducing the lifespan and reliability of the car. This is why it's so important to choose the best - choose TunerWerks, the research and development we carry out ensures all our tuning is of the very highest standard possible. We take great care to ensure that all of our modifications have no detrimental effect on your car.

I don't feel any power gains after ECU tune.

Sometimes, power gains may not be noticed immediately after ECU tune. ECU needs to go through adaptation period. We recommend driving hard for at least half to full gas tank. Another method is to disconnect negative battery terminal for at least 3 hours and then drive hard for at least half to full gas tank. Another possibility is that the vehicle was already ECU tuned by previous owner (it is owner's responsibility to verify in advance).

How can I tune my car?

If you are located outside of Southern California, then you can mail the ECU to us. Turnaround time is 1 business day after receipt. If you are in Southern California, then we can schedule appointment.
