Give EFILive a try to help fool it, plus you'll love the extra HP. BTW it can help in changing shift points.Back in business. The dealer was able to reset the computer and the truck is back to running again. The transmission seems sluggish but I was told it would need to relearn the way I drive. Also have a message on the overhead that says catilist is full needs service but that's not possible, it's not there. Hasn't been there for over 500,000 miles. Guess I'll run and see what happens.
