I do have the IAT sensor in the bottom of the y-pipe 2" from the TB.
The 2007/2008 info I was referring to is the docs from EFILive tech docs. I have read so many docs I can't remember which ones had descriptions I could not find in 7.5Tune.
But I will plug along. I know I can make adjustments but I am having trouble understanding when to know know its right. So is it I get it close so it runs decent then put it on a dyno to know its performing correctly.
I do appreciate your help.
