I honestly would do a leak down test on every cylinder first just to check to make sure its not one cylinder thats gone south on you. I have seen one or 2 customers try to do their own cam installs before and they just happened to nick a valve while bolting the cams down and it will cause just enough leakage for it to ide rough and run rough at low rpm but they tend to smooth out a bit more at say 3500 rpm and above but they also tend to lack the power that they should produce. If you by chance did nick a valve or 2 it will cause low vacume at idle and that will cause an almost impossable to tune out rich condition at low rpm's where the motor isn't so efficient compared to higher rpm's and under boost.

nope not yet... i got home late from picking my car up in raleigh and never talked to him. I told him to lets put the stockers back in and if it still fails compression then juts take it to dealer and get **** replaced... he said he would just rather build it.. If that is the case there is no need to even try to put the stockers back in... I dunno he is a good friend of mine. I will do whatever he wants
