when tuning in SD
Nobody ever mentions resetting the fuel trims. Should I do this before I start..I'll be tuning with WB so unfortunately I won't be using 02sierraz71_5.3 great write up, but nevertheless...I don't remember him mentioning it either. I read the article from Chevy High Performance and they mention resetting the trims.
thnx,

if you disable the lt's you wont need to hit the button everytime just once.

Short of paying for a 2bar sensor and paying HPT an exuberate amount of cash to get 2 bar, what should I do as to be able to tune this gas hog? Unhook the bypass valve so it doesn't go into boost? But then it would be out of whack when I hook it back up right? ugh.

If you have a boost gauge you can drive around hitting as many cells as possible without going into the 1psi range. You can tune all the way to zero vacuum and that should get you buy fine. After all... once you get into boost you are into PE fueling anyway. Tune your PE and you're all set.
