Default still cant get idle tune correct..help..

so make it simple ive been working on my tune for weeks almost months and well im no tuner but ive got help from many tuners on here but i cant seem to solve my idle issues.. truck loved to turn off when parking or when coming to a stop.. ive messed with idle air flow up and down like crazy anymore and the truck just kinda stays up in the rmp.. the cracker if i give it more it starts pushing the truck forward. i have attached a log most of the low idle is towards the end.. ill give gas and then brake and the truck seems to want to turn off.. theres also a spot where it turned off when slowing down and making a turn, it just died on me.. (happens alot while on the brake and turning) im left with no power steering in the middle of the turn and i gotta pop it in neutral and turn it on asap!.. heres the log let me know what else to mess with.. i know we got some good gurus out there..

I don't use EFI or I'd answer my own question, but is this DBW or DBC?

Have you read this?

Idle Tuning - Helpful Info Inside

You might be having the problem he was having with {B4504}. Try upping that a little.

Tune doesn't look good. I haven't looked at a 5.3 VE table in a long while, but it looks stock to me. Desired idle airflow is way high. If I had to guess, there's no wideband tuning going on here, just blind adjustments. Once you get a wideband on it, tune the VE, and do the RAFIG/PN I bet it will drive just like stock.
