tune for 2011 Chevy Silverado

[Rwhite85]

It's been a while since I've been on here been trying to teach myself to tune reading through all the forms I'm starting to think my truck is more of a 2010 than an 11 because nothing anybody says matches my PIDs I'm having a big issue trying to control my throttle if somebody could point me in the right direction. For the most part the truck runs decent I can make it run without the mass airflow and O2s, but I still cannot control my throttle I'm requesting 15 and it's at 22.

Also I hope I posted this in the right spot
2011 Chevy Silverado 1500 4x4
5.3L started out a 4.8L flex
228 intake
230 exhaust
112 separation

also i have a wideband and for the most part it matches the afr my problem is i cant find the pids and cant figure out how to make pids and maps all the help that efi offers is out of date cus does not match the EFI i have
