I noticed a big difference on my Boost with the TRS. So much that I am going to tackle my clutching again to load the motor harder. With my 20 HP Bikeman tune, y pipe, can, billet intake,TRS Valve, custom clutch set up that I did on my own, this is a wicked trail sled to ride. Did a few roll ons with my buddy that has a 290 hp tune on his sidewinder and we were side by side rolling on from 40-100 mph. He got me by two sled lengths once we got to 110 on the dreamo. I was shocked he didn’t walk away from me quicker. This was trail conditions, not on ice.
