Yes on the 9t13c crom transmission would not downshift out of overdrive until you were around 30 mph or you kicked throttle to floor and forced downshift. I have been running the 50 hp tune with out problems and I heard that people were getting better mileage on 80 hp tune. So I installed drove to work and back maybe 25 miles round trip and got the P0088 code and truck ran terrible.
