Boosted or Nitrous?

If your vehicle is supercharged, turbocharged, or running nitrous, please make sure to add the Boosted/Nitrous Tuning add-on to your cart. This is a separate service and is required for proper calibration of forced induction or nitrous systems.

Disclaimer: Your vehicle must arrive mechanically sound and ready for tuning. Any mechanical issues, wiring problems, or additional labor required to make the car tunable will result in additional charges. Tuning time does not include diagnostic or repair work.
