hp tuners programing tips and tricks.

[a.graham52]

hey all, hp tuners should be arriving tomorrow andi ll probably start to play with it Thursday. vehicle im tuning:

2002 gmc sierra 4x4
4.3 v6 5spd.
mods: exhaust and k&n drop in filter with modded air box.
mods in process: modded butter fly valve

symptoms:
high fuel trims (+9 long term cruise)

iv already rapped this thing for vac leaks. found nothing. if you insist i can give you the run down but its too much to type.

so i know i need to start with the VE tables, get them down right and then add timing as nessasary. iv also been following some other links with step bys but they dont awnser ALL my questions.

the thing i have to ask is what tips do you guys have for tuning WITHOUT a wide bad sensor. it is NOT in my budet at the moment.
