BMW PERFORMANCE CHIP M60B40 + 35HP / + 45NM 7000rpm

A Performance Chip for the E34 E32 E38 E31 540i 740i 740iL 840i 840Ci 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 7000 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 7000 RPM and the top speed limiter has been deleted. 

Ignition time + fuel maps changed, more torque at lower and high rpm
