disapointing day on the dyno :(
disapointing day on the dyno :( went to a dyno jet near lexington ky. not sure of the guys name but he has it in his garage behind his house. anyways:
strapped it down and made a pull and not too good. only like 380 rwhp. had a spike in the a/f around 4k rpm, and fuel pressure fluctuated funny. messed with the tune for a bit and it gradually got better but it looked like we were running out up top. fuel pressure dropped like to 35psi, yikes. af never got above 12:1. just couldnt figure it out. my buddy tuning it said something wasnt right so he wanted to stop. i was all for that couldnt afford for something to screw up. made mid 500's with the fuel messin up but i turned it back to like 5 psi. he suggested to change the filter, had a factory filter on it when i changed it today, holds 55psi at wot to like 5500rpm and i stop. so looks like that could have been the grimlin in this case. looks like its back to the dyno to waste some more money. wish me luck

Did you set up a BR Adj FPR and return line? The fueling on my friends STS car was jacking up under boost, but is silky smooth now that the return line and FPR is on. GL
