I know its been awhile but I sold this truck and just bought it back..the guy that bought it just drove it a few streets from me and parked it. I finally had a chance to take it out and run it and it stumbles pretty bad ontop. I took the jets out and unlike I thought it has 79's in the front and 80's in the back. Think taking it down to 73's on both ends it would clear up the top end blurbering?
