When the first M5 and M6 were brought to the U.S. they were de-tuned from their European brothers and sisters. That was a shame as the cars lost close to 40hp. But adding a TMS Performance Chip will get that lost horsepower back! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. As a result there is a 48 horsepower increase at 6000 RPM with a new rev limit of 7200 RPM! Conforti achieved this by tuning the car on the dyno, specifically changing the fuel and spark patterns in an effort to make the engine more efficient when burning 91+ octane fuel. Torque increases similarly in the heart of the powerband. There are NO downsides to installing a TMS Performance Chip; simply put, it is easy-to-install horsepower.

Horsepower Gain	+ 48 @ 6000 RPM
Torque Gain	+ 32 @ 5000 RPM
New Rev Limit	7200 RPM
