E31 Performance Chips: 1985-1995 Cars
Description:
Our most popular product, hands down! Most of our Performance Chips have been developed by Bosch Motronic tuning expert Jim Conforti, with a few custom-tuned by TMS on our in-house Dynapack chassis dyno. They provide the ultimate in performance! Adding a performance chip to your car is the easiest, most cost effective way of increasing your BMWs performance with NO downsides. TMS performance chips are supplied with detailed instructions and are user installed in about an hour. The performance chip optimizes ignition timing and fuel curves which results in increased horsepower and torque. We have dyno tested these chips and compared it to all the others and found it to provide the most
horsepower and usable torque. Must use 91 octane or higher gasoline. All chips are warranted for as long as you own your BMW and also come with a 30 day
performance guarantee; if for any reason you are not fully satisfied with the increase in power and overall driveability you can return the chip to TMS for a
full refund. CLICK HERE BEFORE ORDERING YOUR CHIP.
