please take the advice from the OGs here and dont ---- wit da fmu. i ignored the advice these guys gave me(sorry i had my head up my ***...) and ran/currently running my vortec 12:1 @ 5psi. first of all, an untuned ANY psi gets boring FAST. second, it runs *** filthy rich no matter what, like 1/8th tank for a 1st thru 4th WOT run(for real). it stinks like fuel at all times. it backfires loud all the time. under 3000rpm? forget about it barely fucken runs. also i burst an old fuel line on first nite, that ***** like $6 a foot. gay. not worth it. i though i couldnt wait, and that i was being misinformed by these cats, like they were haters or somethin. WRONG. WRONG. i got a walbro 255 and precision 440s for like 275 shipped. getting it tuned w/ crome pro on friday. the fmu and fuel line cost like 150 and only supports a shitty running 5psi. for 125 more, you can run like 10psi or more and itll actually run good. its a no brainer. plz learn from my ------- mistakes, and takes thes guys advice--its well worth it.
