I've been using the search feature quite a bit today, so I'm looking for some affirmation as well as answers/advice.

2003 GMC Sierra SLT xcab Z71
5.3 ltr v8
automatic trans
373
33" BF Goodrich all terrain ta's
K&N cai
Flowmaster exhaust (forget the name, something like "american classic", single pipe out, to twin pipes in front of rear tire

Trinity t-1000
'87 octane tune
tires adjusted to correct height
torque mgt, "off"

IF i'm reading the tuner correctly, I can increase my shift pressure at WOT for 2-3, and 3-4 under that heading.

Question:
How much is a good/safe adjustment to make? at least to begin with?

Feedback appreciated,
thanks

we dont let you do anything unsafe

mikel,

I am LOVIN' this gadget!
I'm a little hesitant to post my mods, just 'cause they may not be what the more experience 'tuners' would/have done, but...wow!

After completing yesterday's tune, my truck (and of course, I qualify these observations as subjective as right now I'm going by "feel")
feels like its hardly putting out any effort at around town speeds, but really has noticeable acceleration increases, as well as much punchier shifts.

thanks, Diablo.
