"I ran your ecu flash Friday for two hours on a variety of mostly rough rocks and roots and hills. Was very impressed, watching your videos I felt the same issues that you stated. And you delivered it was clean from bottom to top, less smoke and spooge at the tail pipe, strong bottom that now climbs through the mid to the top quicker and stronger and much more capable and fun. The best $250 I’ve ever spent , can’t wait to ride it again."

Does my TPI need remapping?

No. However, manufacturers are unable to unlock the full potential of the engines due to regulatory requirements they need to adhere.

No. But if you would like to use one, our maps are compatible.

Is the idle screw modification recommended?

Yes, but it is not necessary. It will help throttle response.
