looking to do some mod to my rocket. Seems there are a lot of motorheads on here so I'm asking for some info. I don't know what tune is in my bike, I know it runs very good. Can i elimate the cat or" clean out" without tuneboy?? Will it increase torque/power?? will it cause popping?? will the ECM adjust???? What are the positives and what are the negative???
