Gen IV and V motors have active fuel management and this one being a 19, AFM will be turned off at the ECU. The 8L90E will also be tuned for optimal performance. I understand there are some issues with these gear boxes and tuning solves the issues.You going to be able to get the cylinder shutdown turned off in the ECU? I'm pretty sure the later 6.2s have that out of the box. When I bought my 2011, the 5.3 had cylinder shutdown while the 6.2L did not.
