BMW PERFORMANCE CHIP for M20B25 +20HP / +25NM @ 7200rpm

A Performance Chip for the E30 \ E34 325i 525i 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.
