GLS 63 AMG Tune 4Matic (M157) V8 Bi-Turbo
Tuning Tech FS offers performance ECU tuning for the M157 engine that will excel your already potent 5.5L V8 Bi-Turbo GLS 63 AMG vehicle (2016+) to the next level. Our performance tune improves horsepower, torque, and driving characteristics by reprogramming the factory ECU inputs, air/fuel ratios, and increasing boost. The remote tune is customized by data logging that can be performed at a local dyno shop, at the track, or on your favorite back roads. This allows us to customize the car to your specific purpose and need. We ensure a tune that is not only specific to your modifications, gas blend and weather conditions, but rather your true use of it. You will not risk having to ship your ECU. You can flash the car at your convenience instead of the mail man's.
NOTE: The customer needs to data log no later than 1 month from the purchase of the tune in order to receive a custom performance tune. Our software program allows us to keep your factory map at your finger tips and flash back and forth at your lesiure. Free shipping to lower 48 states.
