FITech systems

[Nasty-Z]

I would not run a TBI with a dual plane manifold , TBI loves a single plane manifold , period.

I would have no clue what Dave is doing in the tune but I would suffice to say he is way more savy than I with these systems so I will not question anything there .

You didn't mention cam specs ? Do you have a cam card ? I am assuming you are using the '7427 PCM (Or equivalent)

Suffice to say , I have personally used a TBI on small block Chevy's (And BBC's ) making much more power than your combo , while tuning was challenging , it was not the end of the world .

Something is amiss , somewhere .

Have you considered using a BBC TBI unit ?

FITech is getting a horrible rep in the community at large. There was one guy talking about how great it ran and how easy to tune it was on a facebook page about a year ago, then the truth came out... he was someone getting paid to use their parts with factory in-person support. I would stay away personally, but like anything it can be made to work I'm sure.
