Bonneville Motorwerks
Performance Software

Bonneville Motorwerks tuned engine performance chips, developed by Motronic expert Jim Conforti, provide the ultimate in performance. The modified Motronic software, optimized for 91 or higher octane gasoline, adjust the ignition timing and fuel curves which results in increased performance. We have dynoed Jim Conforti chips and compared them to other brands and found they provide the best performance throughout the entire rpm range. Along with performance increases in both torque and horsepower, Jim Conforti chips provide the maximum competitive advantage through raised engine rev-limits and removed top speed limiters.

Due to the variances in individual vehicle mechanical component condition and the effect of tolerance stacking, your individual vehicle performance results may vary from the performance results listed on this page.

Cars produced from 1996 onwards (OBDII cars) require flash reprogramming via the Shark Injector™, a do-it-yourself engine software programming tool.

Gain even more horsepower by adding a matched performance intake system.
