I have a new transplant into a 69 Camaro and can not seem to remove the VATS. It shows as being removed when I read the computer but it is still there. The engine runs a few seconds and quits. I loaded a Camaro file into it but it ran poorly and had no throttle (this is a fly by wire set up). I had the same problem with an LT1 and had to load a Camaro file and update it with the Corvette calibrations. Has anyone had this problem? Scanner shows no faults!
