Seb gave me a new tune I'm going to try today

UPDATE:

So been driving the Z around after the clutch install. Also replaced the cats with another set of stockers. Idle still all over the place.

I got another tune and flashed it. Was pretty brutal. Just "huffed and puffed" at cold start between 2K and 4K rpms. No clue what he did there.

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!

Well, you were right. Seb set me up with a 2008 ROM and fixed the issue.
