Default What size injectors?

Sorry guys, search is down.

I had my 1999 SS hooked up to a GM Tech 2 scanner today and I noticed my injectors are being worked hard even at idle. I'm scared to go WOT now.

I have a full bolt on 233/239 cammed and 59cc headed LS1. I also have a FAST 90/ NW 90 on it. I always thought stock injectors were good until nitrous and FI were used but obviously not.

What would be a good size to jump up to?

Thanks in advance.

Its saying I need 34#'ers.

Then do 42 lbs. As long as you tune for the injectors then you and your car will be fine.

PM Bob at EPP. He will set you straight on the injectors.
