Ok I swapped from an 85mm intake and tb to the fast 102/102 setup with red top injectors and now my car won't idle under 1400 rpms and is running really fat probably due to the bigger injectors. But I'm pretty sure I don't have any vacuum leaks. Do any of you guys know about what's going on?

Was it retuned for the injectors?

Exactly! If it wasn't adjusted for bigger injectors, it is dumping too much fuel.

No hasn't been retuned yet And is all the extra fuel the reason why it idles so high now?

you need to get those bigger injectors OUT until after there is programming there for them; they will DROWN that engine.

I pulled the big injectors out and put stock back in just for curiosity sake and it seemed to run better and more crisp but was still idling around 1400 does anyone know why this is. No vacuum leaks or anything I'm just stumped and there isn't a hole in the tb blade so I don't know where it's getting extra air from?

It has to be rescaled for the TB, too. It's opening the TB the same amount as the smaller one but the bigger one lets in more air at the same TP.

Exactly what I was thinking. Going from an 85mm to a 102 will let in a great deal more air. You need to decrease your idle airflow rate.

that's a corvette thang


You'll have to re-do this, but he seems to be referring to ETC blade/effective area
