I have completed the update and notice no difference. Maybe this has already been discussed/determined but it must be new behavior/programming of the exhaust valves. Solution, valve controller. I have SST (and MAD midpipe). I leave mine wide open all of the time and like I said, I have not noticed a change with the update.
