OK well this car had this problem awhile back, but it went away for awhile. Now it's back and I'd really like to get it fixed before I come home. Basically when I give it a good amount of gas, it just has no power. If I boost over like 5 psi in 1st and 2nd, it just feels like a total slug. Geo Metros could beat me in a race as of right now. If I stay under 5, then it pulls like it normally would at that throttle level. But give her a lil more and she all a sudden just feels like there is a total loss of power. In 3rd through 5th, it'll do the same but not until like over 10psi. Under 10 and she'll feel normal. I just got done building a lil boost leak tester like VFAQ shows where u attach it to the inlet of your turbo. I've never done a boost leak test but hopefully tomorrow I'll be doing that test to see if there's a leak anywhere. BUT, I mean if I punch it, it'll still spool up to like 15 or whatever, so that's what's kinda strange in my mind. I've been looking up old threads on tuners, and read one about a guy who seemed to have very similar problems to me and it was a bad fuel filter that was the culprit on his car. I'm thinkin I'll put a new one of those in cuz a new fuel filter couldn't hurt even if it's not the culprit. Anyone have suggestions on a decent brand fuel filter? Also if you have suggestions on the best way to do the boost leak test since i've never done one, please let me know. Or if anyone has any comments on what else might bemy problem then please share your thoughts.
Also should i have open the throttle plate while doing this too or keep it closed? I'm guessin open it so that way u can see if your intake mani is leakin, but just thought i'd ask
