Hello everyone my name is Joey,
I finally found an LBZ with only 50,000 on it and couldn't be happier. I am a little worried I might have gotten hosed though. The truck came with a Diablo Predator tuner and the tune was out of it when I test drove it. So being a normal guy as soon as I got it home I put the 120 tune in her. Drove it for about a week to let the tranny learn the new shift points. Last night i took the truck out to beat on her a little bit and see what she would do and it tugs hard unit it comes time to shift. At around 3500 rpms or so the truck falls on its face and holds at 2500 rpms for a long while then shifts and starts toughing hard again. My concern is that the tranny is going out. But im not sure if its the programer , or do i have a fueling problem I am lost. Any suggestions would help.
Also no check engine lights come on and no codes either.
