line pressure?

line pressure?
i just got my tuner the other day. i got my tire size, TM, WOT shift points down pretty good. but when i am accelerating not at WOT it stutters in-between shifts. i think it is the line pressure . so what should I do to stop it from stuttering in between shifts. I have a 03 gmc 5.3l.
and another question I have is how much can I advance the timing with the mods I have listed in my sig with 89 octane?
