ECU Tuning Process: How do I get my ECU tuned?

+ 118 Wheel Horse Power + 134 Wheel Torque Peak Gains


The hand built M178 V8 Biturbo engine from AMG is a powerful motor from the factory proving it is very capable on and off the track, but even a perfect machine can benefit from finer tuning.  Using the latest calibration technology and countless hours of testing, Weistec was able to achieve massive gains in both horsepower and torque through out the powerband.  The Weistec M178 ECU Upgrade provides 118 wheel horse power and 134 wheel torque at lower RPM???s along with substantial gains in the mid and high range, making the power delivery far superior from the factory calibration.
