You need to do a cold start logging your Idle Fuel trims (STITs and LTITs) vs coolant temp to get your Idle airflow table inline... You will need to do this with the truck is in Park and in Drive... Since there are 2 different columns on that table (Park/Neutral and Reverse/Drive)... That will help with the idle so you don't have to 2-foot it. EFI Live has a really easy process called RAFIG and RAFPN that does this, not sure if HP Tuners has it...

Also you might want to bump up the timing in the idle area 1-2* too.
