Hey Chad, I put the DFR Throtle body, fuel control, air box & stage 2 clutch, I already had a header and FMF exhaust tip. I had the dealer install it because it's free labor if I buy from them so I let them do it. They worked on it for days trying to set the fuel controler. The big diff I noticed was when you stab the pedal from a stand still, it screams right up to the rev limiter but when you are running about half throtle & you nail it, it's not that responsive. Seems the dealer had a lot of problems setting it up. They were setting buttons then riding it and comparing it to new RZR's they had on the lot. They claim they could notice the difference, I could feel a difference off the line but not when you nail it when yer going about 30 mph. I'm starting to think it was a waste of money. I have not been to Glamis since the throtle body replacement. That will be the test to tell if it was a waste of money. Sorry I didn't get back to ya in the earlier post but keep me posted how yerz werks. C-Ya
