BMW PERFORMANCE CHIP M50b20 +20HP / +25TRQ 7200Rpm
A Performance Chip for the E30 \ E36 318is is an absolute MUST-HAVE performance upgrade. This chip was developed on the dyno to increase horsepower and torque from low RPM all the way up to the new 7200 RPM rev limit. Our engine management expert tuned the fuel and spark mapping to maximize output when used with 91+ octane fuel. More power, a smoother engine, and better response are the results. Bang for the buck, this is hands-down the best upgrade to do. The rev limiter is raised to 7200 RPM and the top speed limiter has been deleted.
CHIP TUNING 7200rpm and O2 sensor DEACTIVATED, impressive torque at low and high rpm for this engine displacement.
