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.
One pc drive shaft and safty loop. Also some ARP wheel studs, you will need them sooner or later, I got lucky and spun 3 studs off on a run, luck for me the other two
held.
If you are just going to the track for test and tune, you may be OK. (this is going to depend alot on the track). But if you run in any kind of event, you will have to have it. Also, you need a vent hose if you are running an enclosed battery box.
