So check this one out. Just finished up a project on my '12 GT replacing the entire drivetrain; McLeod clutch & billet lightweight flywheel, Calimer state 3 tranny, DSS one piece driveshaft, completely overhauled axle with 3.73 gears (from 3.31). Yes, did the crank relearn (car is Lund tuned). The car now has little to no engine braking. Lund has provided three tune updates now that have not changed anything. Car runs 100% absolutely bonkers amazing. We touched nothing on the engine this project (other than the new files to try and address the loss of engine braking). I've attached a video of a pretty mild pull to 4K in 2nd or 3rd gear and then let off the gas. Very little braking and tons and tons of pops and crackles. It never did this before the project. Any ideas?!?!?!

Is the crackle part of the tune? Taking a total stab here. Excess fuel on over run, rather than fuel cut on closed throttle normally, with timing still firing before exhaust valve opening sufficiently to dump gases out exhaust. You are still building compression and therefore drive.
