Tuning

Tuning is crucial to the health and longevity of any engine build. Flag Motorsports offers LS and LT tuning support for GM ECUs using HPTuners, Holley engine management, Haltech, and MegaSquirt. We also offer automatic transmission tuning for shift points for 4L60/80es, and 6L80/90es. We specifically offer street tuning for driveability, we do not tune for the highest horsepower dyno number possible. In our opinion, it is more important to have a well running and healthy engine than to run an engine on the ragged edge to hit a number on a dyno. We also want to make sure any tune fully accounts for all different driving conditions and is polished in driving situations a dyno can’t replicate.

If you are looking for a tuner for your LS or LT powered vehicle, we have decades of experience. Contact us to schedule a tuning appointment below.
