You should be very careful driving it with out a tune like you are... I wouldn't take it over like 2,500-3,000.. My hats off to you for doing it though! I'm hoping and planning to do a 5.4 2v swap and then mount a lightning upper intake and supercharger I'm glad I ran across this post now I know I can for sure use the 05-10 gt throttle body for it since it also utilizes the double blade TB...

ya seems to work for now, i found my throttle body on ebay super cheap!

If its that easy to do a 4v head swap. Would it be easy to swap my 4.6 2v heads with 4.6 3v heads from a mustang?

Thought about it but never looked into it, the one thing that worries me is vct control, or could you swap to 4.6 3v setup and use 5.4 3v pcm and wiring??

It's been done there was a guy on modded mustangs tht did it... Id go there and try your luck...

The reason I ask is because I just got everything needed to supercharge a 4.6 3v 2010 mustang (pulley injectors etc.) and want to put it on my f150 4.6 2v. Trying to make my truck fast but on a budget lol
