Hi, im planing on running an air gap type intake, i would like to drill it out for 8 injectors like a the tpi's and lt1s have... but i dont want to run all that wiring... what do i have to run? besides the computer to get them to fire right? what's easier to burn chips for tpi's or lt1s and witch cost less? any help would be great!

 

Everything.
Learning to tune EFI takes a certain level of commitment to learn. It's rather mote as to which is easier. It's close to a toss up. The LT1s might be a little cheaper, but they're not forgiving, and power supply problem, can trash the pcm.

 

Stick with the TPI's ecm. We have better help boards than almost anyone else. It will save you hassle of swapping everything else over also.
