Live Tuning


All new Live Tunes include free wideband monitoring on vehicles equipped with an o2 sensor bung. Your PCM will be read and we will modify your stock calibration file for any aftermarket modifications and your driving style. Technician will test drive and fine tune the vehicle after tune is complete. The technician will not diagnose any problems with vehicle not directly related to the tune unless appointment was made for diagnostic issues which will incur an additional charge of $75 per hour. All computers are locked upon completion of tune to prevent third parties from corrupting the file. Computers can be unlocked at anytime; However the customers ECM will be flashed with the OEM calibration.

Before showing up to your appointment, please use the following checklist below as a guide to eliminate any possible issues that could arise during the tuning process. A good tune begins with a good foundation!

We reserve the right to refuse any vehicle for any reason from the tuning and/or dyno process.
