2006 GMC Envoy Denali - 5.3L (M) Engine
w/ Displacement On Demand

Does anyone make a programmer for this? I checked out DiabloSport but their U7192 does not work on the M engine. Also does anyone make a cold air intake or throttle body space for these trucks as well? I've looked everywhere. The only place I found anything that might work is Airaid.

The number one thing I need is the Programmer though.

Also, is there any way to tell when the Displacement on Demand is working? Can you wire in a light or something to tell when it turns on?

Thanks for your help.
