GM “Ultimate TBI Mod” throttle Body [hidden information]

Works perfectly, injectors have a beautiful spray pattern, everything works like it should… But better!

Single air cleaner mount, not the late 2 mounts.

Cut the air horns down and smooth out the transition to the bowls and installed an injector pod spacer.

Modifications allow better and more air flow to the engine. I did add a valve to check fuel pressure but we believe it is on the wrong side of the regulator and doesn’t read the correct pressure… That or my gauge is bad which is possible. You can swap out the injector pod top with yours to get rid of it but it doesn’t affect the way it runs.

Pair this mod with a 2.5 inch y-pipe and better flowing exhaust an
