Looking for a little info. Anyone run HPS, SLP Comp, BMP full velocity and experience performance issues? Spark plug issues? Positives or negatives? I’m Running an HPS on my ‘22 850 na and I’m on the fence with it. It sounds good, and not loud, but I’m suspecting a couple performance quirks. Not really wanting to advertise quite yet since I don’t know for sure. Anyone else?
