Be gentle with me, I'm learning my way around HP Tuners. I have an E38 out of a 2007 Silverado, setup on a bench harness. I go to System, General, and there is no VATS there? I have done a VATS delete on an earlier G31.
I am in advanced view.
I've attached the file:
2007 Silverado 6.0 Alum heads.hpt
Thanks for your help.
