This is a 2005 GTO with a TVS 2300 231/248 cam with -5 overlap, 418 cu in. 11# boost, 2 bar sd, 4l80, E40, Fast 65# injectors, boost referenced return fuel system.
It stumbles off idle every time even when the car is moving, if I am off the gas.
Stumbles at frame 1781,2010,2525,2527,3231, 5268 and a few more in between.
I have attached the tune and the latest log.
Thanks for any ideas.
