i bought a new 2010 Ski doo Renegade 800r adreneline. Its almost got a 100mi on it now after this weekend. I cannot believe the power this has even at 10%hp decrease due to the 300mi break in period in the ecm. It is one HELL of a step up from the yamaha phazer i had with a wopping 80hp. I mean the thing goes 0-100 with out touching a ski on the ground even at a 137in track! at 105 the ecm levels out and wont go any faster, might be due to the break in period because its still pulling. I guess 150+ hp will do that. I seriously have a smile everytime i clamp the trigger and the thing pulls and pulls!
