Update:
Well Boys and Gals, Looks like Seb did it. One of the main issues was getting the car to go through idle relearn. The rpms would never settle below 1,100. Turns out, the 2007 HR ROM has a hard time with this. He set me up with a tune on a 2008 ROM and viola. Pain and agony vanished. Idle is set for 850, just sits there and purs.
Going to have to tip this guy real good. Went well and beyond trying to hunt down this issue.
Thanks for the input and advice everyone!
