I am hoping that there is a gearhead out there that can help me as my dealer is out of ideas. I have a 2015 Pro 800 with an SLP pipe, PCV, Bikeman air box mod, SLP intake kit, Vforce 3 reeds and RkTek head with stock compression domes. I run 91 octane fuel with Lucas Oil octane boost from the same gas station as everyone else. All of this was put on from new and worked great with no issues first year and a half. Then it would DET both cyls and shut down at WOT every once and awhile. Didn't matter if I was pulling a hill or ripping across the lake. Now it is much worse, every ride out and a few times a ride, still at WOT though. It is very random though as I can pull the same hill 5 times and it will only do it once. The sled is not over heating or over reving as I keep an eye on that. We have programmed in the latest map from SLP for my altitude which is 0-6000ft, tried another PCV that we know works checked the TPS and it still does it. The only thing that has helped is we turned on the Ethenol map in the Polaris ECU. Pulling my hair out as this usually occurs at the wrong time on a hillside. Please help me enjoy hill climbing.
