I f i WERE YOU i WOULDN'T put 10-11 psi of boost to a stock block with out o-ringing the head gaskets. we kept blowing gaskets trying to do that further more if it has 19 lbs injectors you definately need to upgrade them and the fuel pump to run 10 -11 psi otherwise you run the risk of running it lean and then pop goes the weasel!!! anyway stock with 5-7 psi Most cars I've seen put about 275-280 rwhp down if that's the only mod you have I just saw a stock one on a dyno withe 5-7 psi make 277hp

I also completely tuned the car myself using. Most of the time I used a dyno and a wideband, but sometimes I had to settle for tuning on the street without a wideband. Which meant that I had to force closed loop and tune using nothing but fuel trims to slightly adjust the MAF transfer until I could get to a dyno to verify the results. And I did the tuning using a Tweecer RT which many people are afraid to even think about touching because of how difficult it can be to use if you don't know exactly what you're doing.
So given that, it's probably safe to say that I have at least a slight amount of knowledge when it comes to my car's setup and what it can handle. And that being said, I have absolutely NO problems running 10 PSI on a stock bottom end with the stock intake and heads. If you kept blowing gaskets because of that then you were either using a ****tu gasket or you guys did a ****ty job tuning it and were leaning it out too much.
