Guaranteed to outperform, all chips have a 100% satisfaction guarantee. All programming by default is designed for 91 (95 RON) or higher octane fuel usage. If programming for 93 octane (98 RON) fuel is preferred, please note your octane program preference in option window provided. Also, unlike some other chips, our chips will not trigger your check engine light. Guaranteed to outperform - even your current performance chip, all chips have a 100% satisfaction guarantee.

Stalling from the installation of a lightweight flywheel and clutch is now history, guaranteed to be fixed by our latest most advanced program solution, or your money back. Not only do you have to worry about stalling from the RPMs subdipping below idle on decel and between shifts, but our newest code actually helps with clutch engagement off the line without excessive clutch slip - minimizing wear, while further compounding the throttle response potential of the lighter flywheel and clutch. Former customers are welcome to have their chips updated free to the latest LWF coding. Contact us for further information. . Please select the appropriate setup in the option box below.

Chips customized and specifically dialed and tuned into your motor available in the Custom Chips and Dyno Tuning section.
