Don't be so quick to say it isn't the fuel pressure! I'm running the same kit on the same yr sled and I was reading all this info on here last yr about FP #'s so I raised mine up from how my dealer set it up..... ran like an absolute bag of crap, acted just like a really rich carbed sled. Worst day in the mtns... Went back down to the original setting of 31psi and it's been golden ever since. Dale might be great to talk to as long as you ride in the same elevation range as he does! I ride mostly at 2-6000' and when I called to quiz him for set up advice he really didn't have any input for me for his own kit. Don't get me wrong, he has a great product and user friendly, just would be nice when spending 6 grand on a kit/install you could get a bit more feed back to make them work.
