Hey everyone. Ive just bought my first camaro, its a 2002 z28 a4 with 126 000mi. The car seems to run fine and the motor sounds healthy but when i put it on the dyno last week it only made 226whp and 244wtq? Its 100% stock and the runs were made with the maf unpluged, could this cause the numbers to be that low?

Yah im going to pick up a stock maf later today and then ill toss it back on the dyno maybe tomorrow and see what happenes. I did a few pulls with a 5 wire truck maf pluged in and it made even less power?

Think i may of found the problem. I just decided to put a fuel pressure gauge on the car to see what the fuel pressure was doing and its sitting around 30psi and drops down around 25-20 when i rev it up. Ive read that the pressure should be up around 58psi and should drop when reved up?

So i did a walbro 255 swap in the car last night and that really woke it up so it must of been right lean. Still dont have a working maf for it yet but ill try and toss it on the dyno today before the end of the day and see what it makes this time. Ill hook a whideband up to it this time and see what the air/fuel ratio is like. What should a stock ls1 run for afr mid 13's?
