stprorolla49, are you still running the stock midpipe?
Negative, I'm running a Magnaflow catted x-pipe. Today Kevin hollowed out the cats, they were destroyed inside. He then made a few more pulls, with the best resulting in 388/386@6500 at 12 psi. I will NOT be revving the car that high ever, I normally shift around 5700-5800. Still don't know why the boost is at 12 psi, but doesn't matter much because at 5500 which is closest to the point I shift, it was at 10 psi making 37xhp (can't remember). He said the tune is safe and the car runs awesome now that the exhaust is free of shit.
Although I was expecting higher numbers, I am happy with 388 as it is just a street car, and almost 150rwhp more than I had. I want my stock shortblock to last for a while so I'm going to take it easy and enjoy it.
Tomorrow he will be making a bunch more pulls, fine tuning a bit, and taking videos. More to come tomorrow!, stay tuned!
