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.
The 2.7 liter inline-6 is a torquey car, however,
performance drops off greatly after 4000 RPM. With a TMS Performance Chip power
is boosted at all RPM but most importantly in the upper RPM. The car really
feels more alive! 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 engine more efficient with this fuel, gains in horsepower and
torque are achieved as well as making the engine run smoother. NOTE: your car may have a replacement DME ending in 021. Our chips will work in this replacement computer as long as the existing chip is not soldered.
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 a huge 29ft-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
engine more efficient with this fuel, gains in horsepower and torque are
achieved as well as making the engine run smoother.
Note: we will need to know the number of pins on your
original chip. It is either 24 or 28 pins. Thanks.
