CHIP M50B20 M50B25 + 20 HP / + 30 TRQ 7200rpm

Chip for the E36 E34 320i 325i 520i 525i 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. Engine management expert Jim Conforti 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.
