Lost Power

Lost Power, NEED HELP!!!!!

I am so mad, I just did H/C/I on my car. It dynoed 290rwhp. After about two weeks of driving it seemed like it lost power. So i called up the shop that did the work and they said to bring the car back. So i did and i was right it dynoed 261rwhp. He let the motor cool and upped the fuel pressure. Put it back on the dyno. This time it dynoed 265rwhp. He did the same thing a couple more times and it got back to 281rwhp. But he said he should not have to up the fuel pressure to get back to my original 290rwhp. Does anybody know what could cause this? He said it could be running to hot or maybe the fuel pump.

maybe it needs a custom chip burned?

well what did the guy who dynoed the car say? i love all these dyno shops who r so quick to take your money and claim they can pinpoint driveability problems and whatnot and when it comes down 2 it the only thing they know how to do is strap it down and run it. does the car have cats? they could be clogged. this guy was just playing with fuel pressure, what was the air fuel curve like when he was dynoing the car? sounds like u should go to a new shop.
