when i first start my car it runs rich as it should, but even after its been running for 15 min its still really rich. now the messed up thing is that when i try to drive it i get really high knock counts in and out of boost (2k rpm). ive did a blt to 15 lbs and it takes about 1min to bleed most of the way out, so its not a really big boost leak. i recently redid the head with bc 272s, 3 angle valve job, etc. it ran fine before this. what could be wrong. any suggestions will be grealy appreciated. ive had the car for about 6 months and its sat longer than ive drove it and im about to sell it, but i dont want to. thanks in advanced.

It is a boost leak. Why did you test only to 15 lbs? What fuel mods do you have? What fuel management do you have? What turbo are you rocking?

Wow, you have a tune of things. Did you lose your tune? Did you turn off the battery or blow any fuses? Boost leak test it to like 20-25 psi since you have a 20g. Also, do you have any logs to post up?
 
i seriously cant even drive it to get a log (hardly wants to move) and if i could drive, i cant load it to my computer to show u whats its doing. i dont think it PK at all. my WB jumps all over the place at idle as well. its weird, it was fine before. i just dont understand
