I was looking at my adj para. I noticed tcm adjustment was not there .
I have installed the 87 tune , 09 gmc sierra 5.3l 6l80e .
I would like firmer shifts ,
the tune has greatly increased my mpg ,
also the only mod. I have done is add a k&n 63series cai, I would like to add more fuel in the idle to 2000 range

I would like firmer shifts , Try and reinstall the same tune, do not go back to stock. If it does not show up post up a copy of the xml file for the DS guys)

Do not just make changes without logging, go here for how to adjust GM vehicles:

if there is no TCM support you probably need to update

I am running the current update
