4.6 to 5.4 swap? BILL....HELP!!!

[CageFighter_Dan]

That's exactly how I am driving mine every day right now with the original 4.6 pcm while I have the 5.4 engine swapped and installed, so far all I notice is more power that's for sure, idle is just a little rough due to the 4.6 using size 19 injectors and the 5.4 uses size 24 injectors
It is still very drivable! As well my shift points between 40 km and 50 km is a little chopping and bogs same as 80 to 103 km all of this will be remedied when I get the tuner with the custom pcm flash that bill is making for me, will be here monday, trust me! Use the original 4.6 pcm computer and u will be able to use it as a daily driver while waiting for your gryphon from bill or start the order process now, it will be the same set up exactly as mine
