2005 Chevy Silverado 2500 w/ 8.1L throttle sticking

[Anders_Y]

I installed the latest Diablo Tune on a 2005 Chevy Silverado 2500 with the 8.1L gas motor. Odd thing happens...when I press the pedal further than 1/4 throttle, the throttle sticks wide open for about 30 seconds. Wild ride! Any ideas Lew? Haven't tweaked the default yet, just trying to get started.

wow, odd... no, I have no idea man.... will have to wait til the other diablo techs see this, maybe they have an idea....

Is it definitely tune related? I can think of a bunch of things that could cause this unrelated to the tune.

[Anders_Y]

Wasn't doing it prior to the tune. When I selected the program, there was no 8.1 under 2005 2500, so I selected the 8.1 under 1500, could that be it? Going to go back to factory and see if it continues.

please load the tune then post the backup and last tune written and we'll fix it.

Damn Mike! Working on the weekend! I appreciate it, and will do as soon as I have a second. It'll probably be this week.

Here are the files. Here are the stats on the truck...

I chose "with ETC" because it is drive by wire.

I have a 03 2500hd with the 8.1 doing the same thing but I have the predator tuner new to using programmers but if you tell me what setting you did a mod to I can probably fix it
