Our car was going in to fails afe during some burnouts @ the track. We would reload the tune and it would be fine. Some of the sensitivity can be taken out with a tune change. That fixed ours for now. If the TB sees something it does not like, it will go into Fail Safe.

Anyone know of a upgrade to the intercooler on the 5.4. Not talking about the heat exchanger by the radiator, I mean the part that goes under the blower. I think our 25 pounds of boost got the best of mine.
The UCA will help, just not sure you will notice it that much. I went from a 1.55 6o ft to a 1.47 60 ft. But I changed upper and lower at the same time. The lower did help with the wheel hop.
