"The 1989-93 535i is a powerful car, however, BMW didn’t spend any more time tuning the car than they had to. The TMS Performance Chip for this car was tuned on the dyno to yield as much performance from this engine as possible and still maintain its great reliability. 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.
Horsepower Gain
+ 43 @ 6250 RPM
Torque Gain
+ 21 @ 2000 RPM
New Rev Limit
6800 RPM"
Dette er jo estimerte tall, så 30hk ut fra chip ser jeg ikke bort fra!
