Hi guys First post at this site, but I have been viewing for months. I have a Diablo Intune and have been going back and forth with American Muscle. First was a pulsating idle (car was quick but it needed fixed and they did). Second was a complete engine shutdown to idle at full throttle from 3rd to 4th gear and no other gear. This is during drag racing and this is very irritating. Anybody else have a problem with this tune.? Is this a Torque management issue? I have a 2013 GT with a cat back and k&n.
