This weekend i was in detroit and i rode with a couple of friends and my cousin. My cousins friend, my cousin, as well as me have 929's but i have a pc in mine. While going threw traffic (at excessive speeds), it seemed like they were toasting the crab out of me. I know for a fact that stock 929 or a 929 with a slip on goes at least 175 max. I was maxing out at like 150. Does anyone know what is going on?
