I have a complicated question for you concerning my regen. I'll try to describe it in short, but I have a feeling it will take a few messages to answer it.
When new, the truck was flawless, I only knew it was in regen by the mpg and tone of the idle as well as the exhaust brake would engage at idle. The reflashing of the ECM in 09 caused some odd problems.1st, the engine would stall before starting the regen when idling at a light and I engaged the clutch and a few times in between shifts. 2nd the throttle would stick after 2000 rpm and cause surging, when excellerating, and I suspect that took out my clutch. The dealer confirmed regen with their computer connected, and the tech as well as the trany tech took it on a test drive.
