Adding a TMS Performance Chip gives you the biggest bang for your buck! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. While not exactly producing V8-levels of torque you will definitely like the 38ft-lb increase at 3500 RPM - right at the start of the power band. The best thing is that there is NO downside to installing a TMS Performance Chip. Turner Motorsport has been in the BMW chip business for close to 10 years and all chips are dyno-tuned to achieve optimum performance and safety. As an added feature, the top speed limiter is removed. Premium 91+ octane fuel is required.

Horsepower Gain	+ 39 @ 7000 RPM
Torque Gain	+ 38 @ 3500 RPM
New Rev Limit	7500 RPM

User review:
"Thanks TMS!!! I received and installed the TMS 'chip' into my weekend toy a 1991 M5. It dropped the ide from 1000 to 750, I swear it brought the torque curve down. It definitely smoothed out the old girl and put the mpgs on the rise. The limiter is up to, I don’t know where, but I buried it in the red in thrid gear. For such a simple upgrade the results are remarkable and for the price theres no way to beat it. All my fellow enthusiasts definitely say they can tell a change. I am all to thrilled with this purchase. I thank you again TMS! You will be seeing my business in the future. Keep up the good work. Thanks. -Nathan W. Bailey
