My Raptor (Barker Duals, K&N pro flow, PCIII) won't even get close to my stock Banshee with only T5s, +5 timing, 145 psi. Didn't really run from a dead stop, just noticed that the Banshee pulls away from the Raptor in every gear. I wasn't riding either, I was in my Prowler, but both riders said the Banshee was faster. WTF is wrong with the Raptor! I installed a map (from raptorforum.com) for the Barker Duals and pro-flow K&N. I have yet to unplug the speed limiter (or whatever its called) that retards timing at high speeds (5th gear), because I can't find/get to the plug. Raptor gearing is stock. Banshee is 15/41.
