QUOTE: How is the livernois tune, did you take your truck to them? I have been talking to them and thinking I'm gonna take it there in the next couple weeks. Another question for everyone is my trans shifts great except 5th to 6th just started having a big slip before 6th gear catches any known problems? Doesn't do it every time but more often then not. I have been not letting it go into 6th when I have been driving it lately.
All in all I am happy with the tune. I took the truck to them and they did it on the dyno. Only slight issue I have is at zero vacuum it has a slight surge that we never did get out of it. Livernois was thinking maybe different injectors. I would use them again if I needed a tune.
For the trans, I would drain the fluid and install a new filter just because. Maybe pull a fluid sample and send out to lab for testing, that does not cost much. Mine has never done this, and would be of some concern.
