BMW PERFORMANCE CHIP M20B27 + 25HP / + 20NM @ 5500rpm
A Performance Chip for the E28 E30 E34 325e 525e 528e 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 5500 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 5500 RPM and the top speed limiter has been deleted.
