I doubt the stock cams and intake manifold would be able to take advantage of the additional airflow provided by a bigger TB. If you have a decent aftermarket air intake then you have already eliminated the main airflow restriction. At the stock power level the ford TB is more than adequate. If you look at most of the 05+ mustang blower and turbo kits they use the stock TB FWIW.

Actually there are gains to be had with a different TB but I just would not trust an aftermarket one with these fly by wire controls. Like I said I have heard too many horror stories with them. However the '05+ mustang crowd has recently started using the GT500/V10 TB and have seen increases around 10 hp on n/a motors and as much as 20-25 on FI motors. This is a great alternative since it is a Ford part and relatively cheap. Unfortunately these will not fit our trucks so we are SOL. I am interested not so much if the one you are getting will make more power but how much it will affect drivability and tuning. I will be keeping an eye on this one.

With your troyer tune do u have to use Hi-Octane gasoline? And could you post a pic of your AF1. I had one on my Lightning and am considering it for my FX2....

I scrounged up a pic of my Air Force 1 installed, but it's kinda dirty.

getting it steam cleaned probably next week, and with that jlt intake and 3" straight pipe id say the tb is now the only thing restricting it
