I install the tune just how it reads and when I take it out on The road the truck is a dog has a hard time gettin to 70mph went back to stock ran fine put it on my bully dog and ran fine all I have done is a cold air intake and exhaust and come 2marrow a boost increase vavle could it need a custom tune or I'm I doing something wrong?

I have never seen or heard of such an issue, unless the BD tool is not actually putting your truck back to 'stock' in which case yes, i could see these types of issues.

It's going back to stock bit it almost feels like your hold the brakes when I put it on the predatorit just came in the mail yesterday kinda bummed but if you come up with something or have something I can try let ke know and do I need a custom tune for what I listed?

[mikel]

no, the tunes we provide should work in any and all duramax's, there is likely something on the truck that is not right...

I guess I'll look into it myself but when I put it back to stock of the predator it runs fine I want this to work I've heard nothing but good thing just gotta find them I guess
