A custom tune (also known as ProTune/E-tune/Dyno tune) is a tune that is created for your vehicle. The tune is specific to the modifications you have installed on your vehicle and any fuel of your choice. The tune is tailored to your vehicle via datalogging. A custom tune is the best way to make power reliably. We provide tuning for stock or aftermarket turbochargers.  As well as many other bolton modifications. There are no requirements in order to get your vehicle tuned outside of having a tuning device to flash the ECU. While we are remotely calibrating your vehicle you will be required to datalog multiple parameters using your accessport. This enables us to see how your car is reacting to each change as if were there tuning the car in person. Each vehicle/modification list will take a different amount of time to complete no two vehicles are the same. Standard vs Lifetime Tuning What is a lifetime tuning package? Lifetime tuning gives you free retunes for part changes after you've started tuning. No matter how many parts you change on your car you will continue to receive revisions free of charge. The only exception to this is tuning for the addition of an aux fuel kit or any other controller that requires programming With the Standard Tuning package you will get a custom tune, and revisions only for the modifications you currently have on the car. Any subsequent mods after the tuning process has started will result in a retune fee of $100. If you change engines or turbochargers you will be required to purchase a new tune.
