Not sure if maybe I just never noticed before or what, but I also had my ecu flashed with the APR program today. I love it, runs great, performs so much better now... BUT I noticed after I shut it off when I got home, it made a few clunks. Almost like "dieseling" or maybe something clunking or rattling from the engine rocking at shut off... Really didnt like it.

Any ideas? Is it possibly linked to the ecu tune? Like maybe with the new timing curve it knocks or diesels after shut off? Or is something wrong?

Any help is appreciated as always guys. Thanks in advance.

 

Doesnt sound like a motor sound after all. I think its play in the motor mounts or drive train mounts. Seems to do it more after driving a while.

Is there a way to install the APR snub mount WITHOUT removing the bumper? I am not really cool with removing it...
