One of our TT members sold his BRP, but the new buyer didn't want the Edle, so I bought it this afternoon, and installed it: Yeah-baby, what a difference! - Total transformation in throttle response - Starts in one kick - Better sounding/running motor - Flattened out the bump in the power band No change in the top end at all, and no 'big' power change, accept down low: whack the throttle? Better be holding on tight, cause the wheel will come up every time, no matter what. Virtually no bog or hesitation. It runs as good as my 450X does down low (but with more muscle). Well worth it if you do any single track or really slow stuff.
