Help, Truck dies when I put it in gear!

[ASTAR]

This is a double post cause I figured that the injectors would give it a reason to be here, I did a search and read about other people with the same problem and used a cold weather reflash at DC to fix but it was for older trucks than mine it seems.

I just had some EDM mach II's put in and I can't go from P or N into Reverse or Drive without the truck stalling! It sucks!

Any ideas? I plan to call Don and ask what he thinks but I figured I'd check here first.

Ive seen trucks with DTT autos do this, But thats only because of the 93% converter! But not to familiar with it from injectors.
