Thanks for the reply!

Well, let's take a hypothetical scenario. I'm brainstorming an engine that I might actually do. A 454 big block Chevy with a "Thumpr" cam and FITech TBI. The cam is 227/241 with 107 lsa.

What would be entailed in making it run? How would you tune it?

Presently, that engine has one of Comp Cams biggest 4x4 cams in it. It has 111 lsa, but still has a very lopey idle because the duration is 234/244. What would it take to tune FITech TBI for it?

You mentioned what all you could do. What can I, an EFI newbie, accomplish??

;~)

Thanks again,
