Cat Cams in Europe didn't even have any dyno info on duratec V6's, so I didn't want to go through them and be the pioneer of sorts.

Kinetics would be my choice. They build Leo Capaldi's engines for his race Cougar. They have a few profiles on hand or they can build to suit. They were having issues with their beefy NA 2.5L's stripping teeth off the gears in the transaxel
