Joined the forum to resurrect a 1992 GMC Typhoon. Overhauled the engine but the tune that is still onboard is overfueling. Got the ALDL cable and downloaded Tuner Pro RT so will try my hand at getting back to a stock tune and going from there.

Sounds like a fun project. Are you rebuilding the truck stock?
