horsepower and usable torque. Must use 91 octane or higher gasoline. All chips are warranted for as long as you own your BMW and also come with a 30 day

E24 635CSi Turner Motorsport Conforti Performance Chip
(more info) The 3.5 inline-6 is a torquey car, however, it could be a
little more powerful in the upper RPM range. With a TMS Performance Chip power
is boosted at all RPM with over 20ft-lbs of torque gain at only 2000 RPM. This
chip was tuned on the dyno to yield as much performance from this engine as
possible and still maintain its strength and durability. Jim Conforti tuned the
fuel and spark maps to take advantage of 91 octane gasoline. By making the

E24 M6, E28 M5 Turner Motorsport Conforti Performance Chip
(more info) 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.
