TBI mod questions

[Cadon69]

On my 95 I plan on doing the afpr from rvmorse. Also I already replaced my fuel pump with the vortex one that puts out a ton more psi.

Actually, to answer this question, one would need to know not only what your FP is currently, but what other mods you may have made.

Just these TBI mods, Volant cold air intake, exhaust and Edelbrock 3704 intake nothing crazy

Im gonna find out my pressure and maybe do that if needed

I think someone told me that the 95s had the pressure turned up already

I was a GM Parts tech throughout the 90s. And that's a new one on me.....

You bet. In my sig I have the 89 listed as a dual tbi. These guys have what I need to make that function properly without blowing out the quad drivers in the ecm.
