Help me understand this as I might be mistaken the two. I have been playing with off throttle timing by lowering it in an attempt to get a mean burble from the exhaust on deceleration or coasting in my ls2 GTO. I used to have it ever so slightly but it seems to have gone away. The GTO just doesn't sound as mean when compared to my jeep 392 running a livernois tune. Don't mistake this for me wanting pops and bangs. Just a nice growl when downshifting or coasting to a stop.
Am I confusing DFCO and engine braking with off throttle timing?
