Having looked at these stats again, it seems as though everyone is chasing Ski-Doo's 800R motor as far as pure stock power production. So with a Y-pipe and more, this sled will most likely be a 160+ hp machine. This problem is widely rep. Another dyno-shop, DynoTech had success in reducing fuel flow from 110 lb. I would like to see it run good and stay with the guys for a few rides.
