Should this be working as soon as u let off throttle? Or that delay is not normal. Ive asked a few other guys but they had 485s and it was a Pete, but they say there is no delay.
I will check the things u mentioned. Thank you!

Would a bad sensor make it delayed like it is, or make it seem like there is no difference in engine brake performance from #2 or #3 setting? Because setting 2 and 3 seem to be working the same. I feel no difference when i switch between them. On the Cats its a noticeable difference. Was thinking it was just that way on this motor. No codes stored for anything engine brake problems.
