trouble with my 2500hd chevy 6.6 duramax

I have been having trouble with my truck going into limp mode if I get on it very hard for too long. I have a bully dog on it but with it on or off makes no difference. Took off cat recently and helped some. also replaced fuel filter. Im up for any other suggestions. it is a 2005. I am also thinking about an EGR delete and fingerstick..not sure though.

Just a hint this is a feedback section for site rules and such not truck troubles. Try getting a mod to mover this to the duramax tech section.

Might get more help if ya posted this in the GM forum instead of the suggestions and feadback. Also wtf is a fingerstick?

woops already treed

Can we get the mods to move this to the LLY section?


What limps? does it throw and overboost code? Or is the tranny limping?
