First let me tell you what I have done to the car. I rebuilt the engine and put in the poston 107t cam w/high rev lifters and springs, chrome moly push rods. I did a three angle valve job on the heads and ported them. I also installed a 160 degree t stat and the ultra chip with 7 settings and a hooker 2 1/2in. exhaust.
I was driving the car nicely for break in. The car was acting great, it would build boost fast even at about a 1/4 throtle and spin the tires shifting into 2nd. But when I hit 800 miles and decided to get on it for the first time it hit 15psi then dropped to 8psi and retarted the timing 1.7 degrees. I set the chip at the fourth setting and hit 17psi but then dropped to 11psi and the trans. would not shift into 3rd until I backed off the gas. And all this time my knock gage didn't move. I have no idea whats wrong. At 1/2 throtle the car pulled 11-12psi when I put the stock chip back in but when I push it passed 1/2 it runs like crap.

the problem was the chip the ultra chip with 7 settings. because I have a pit bull chip in it now and now I can't floor it because I hit 25psi and it started to knock. Guess it's time for a blow off valve or something
