Ok so I got my pcm back from intense and the fuel trims were still in the negatives when i started it. So I drove it around for a bit and the fuel trims sort of mellowed out in the low numbers +/- 4 or 5. After I drove around abit longer the trims stayed in the positives and cruising and idle the trims are at +16.4 and driving it up to speed it would go to + 5-7. When I did get on it I got about 2-2.5* of knock. When I had problems from the pcm before I did a fuel pressure test and all the numbers were somewhat low but no one i talked to said they seemed to bad. On with out engine (48psi) Idle (44-45 psi) 2,500 rpm (48psi) and rev limiter (50psi). I wouldnt think my pump would be bad probly do need to change the filter its been awhile. Any ideas? Positive number means it has to add fuel correct?
