When the first M5 and M6 were brought to the U.S. they were de-tuned from their European brothers and sisters. That was a shame as the cars lost close to 40hp. But adding a Turner Performance Chip will get that lost horsepower back! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. As a result there is a 48 horsepower increase at 6000 RPM with a new rev limit of 7200 RPM! Conforti achieved this by tuning the car on the dyno, specifically changing the fuel and spark patterns in an effort to make the engine more efficient when burning 91+ octane fuel. Torque increases similarly in the heart of the powerband.

Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour.

"I went with the Conforti that I bought from Turner and am very happy with it. There is no noticeable (to me) change in fuel consumption. I have slightly better pop in lower gears where , gawdknows, the car really needs it and the car certainly pulls faster and stronger at the top end." - Taylor, Montreal, Canada.

"I have just installed the Conforti/Turner chip, actually increased my gas mileage by 1 mpg, but the power curve is much better and the movement of the point in the RPM bad where the engine limits itself is so much nicer. I am very happy with the change." - Rick, California.

"I tried Dinan and BavAuto�I like Jim C's the best." - Joe, Connecticut.
