Im going to the dyno on the 17th with these mods. [email protected] filter, gutted cats and [email protected] race baffles in the stock cans. The elevation where I live is 2700ft. My question is should I buy a power commander before I go or just dyno now and see how it turns out? Im really hoping for 160whp with these mods. Bike pulls very strong. Its also geared down two teeth in the front. Dont know if that will affect anything. I have a 16 tooth and 17 also. Any advice is appreciated.
