[QUOTE="Brad.S.19, post: 1054584, member: 12605"] Okay borrowed a tester from a buddy, results from the pass side as follows had zero issues on the drivers side all 415 after 5 full cycles. #1 410, #3 415, #5 415, #7 415 Running test #8 650 and #1 645 ish the rest where around 650 I think I may have a cracked injector cup or two. Still lacking power till upper rpm, speedos off 5mph and knock is still present while cold on #5. So I am thinking fuel filters in the tank are clogged and maybe IPR/ICP issues need more testing injectors have "haze" @ cold start over two days of sitting or below 60*. Another thought is weak fuel pressure and bad idm the other thought is fuel pump is worn. Last thing I can build 2600-2700 icp @ 40% duty then it basically drops off a cliff automatically says no more pressure. [/QUOTE]
