Okay not that this is a bad thing but since I have gotten the Cobra back it actually feels a lot stronger. I mean 98% of the time at the top of 2nd gear I just start roasting the 275's. It only happened occasionally before I had the rebuild. I also noticed that the blower is a lot louder now than it was. It's an SQ and was very very quiet before but now it's just a little quieter than a standard S trim blower. And last but not least I pegged 9.5 psi today coming home from lunch :-? . Do you think the shop switched my blower head unit???? I'm going to cross check my warranty serial numbers today to find out but what the hell do you guys think is going on?
