Nope, the guy had my car for weeks and I didn't physically see him install it, just saw the finished product. I'm heading down to the garage now to switch it out. I have zero problems running the 100 shot, do you think I will have any at all with the 150 shot? I mean in terms of detonation, running rich or lean (clueless about those terms but I hear them a lot) or anything else? Thanks!
