TWM is the company that Roush uses for their FI. They can be purchased from a guy on this forum THOR. I use a FAST XFI and have had no problems. It is pretty easy to install. The hardest part is welding a bung on the exhaust manifold for the O2 sensor. It has a nice smooth power band that is easy to drive hard and hard to drive easy

I have a picture of the cam label in my pictures.

Rwilla, what is your set up for fuel delivery? If you have pics it would help!

I am curious to see what others have done.

My Roush 427IR uses an Accel DFI system. I'd heard they'd switched to a new controller and swapping for the new one was possible but it looks like they may be able to whip it into submission. More to come.
