Ok guys still need some help!
My LT4 had a BAD stumble at high rpm's after i deleted the cats and i assumed it needed a pcm program so i sent it off and had that done and it runs alot better but i still have a small stumble/miss at high rpm's. And jusy for info. The stumble just all of the sudden started after ik changed the factory exhaust with all aftermarket parts and deleted the cats completely.
ANY IDEAS OR SUGGESTIONS??
THANKS FOR ANY INPUT!!!
