So I've be logging and tuning for my ve table. I've changed my ve table a few times but now as I come to a stop the truck surges really bad and turns off. or sometimes even when I put it in gear what gives? a bad log?

Revert the idle area of the VE table back to some previous values...

what cam specs do you have...?

if your cam has a lot of overlap, it will let unburnt fuel thru which shows up on the wideband as lean (due to the unburnt oxygen)...

comare the idle area of your current VE with a previous tune.

5.3 60lbs injectors 224/228 .60X .598 114 lsa 3k stall.

I'll try it maybe when i'm trying to smooth the table out.

LS1 I guess it's an 04 silverado pcm it's a 2 wheel drive auto with a 4l65e. 3k stall. procharger 12psi and 87mm tb and Fast LSXRT intake, 160 thermo, efans and the above mentioned. I really wish we had a how to in order for everything something like.
(I'm a newb so I need things like this so I don't have to keep asking questions with lots of screen shots)
step one upgrade OS
step two set up Map if needed
Step three set up injectors Injectors
step four do VE tune. for Map.
Step five do CAL ve tune for MAF.
Step 6 setting up timing
step six Idle
step 7 change transmission setting
