Taking my first swipe at this project. 2000 5.3/P01 ECM. Cannot get a steady idle, seems like a vacuum leak but engine passed a smoke test. I turned off alot of tables to simplify but ......TIA

Set up is: E85...160 lb. FIC injectors. Dual AEM fuel pumps.. BW twin 64.5 turbos..Tooley stage 3 cam 230/235 duration. Stock truck intake and TB.
Here is a short log file....needed a little throttle to keep it running
Go to Engine diagnostics--Airflow-- and zero out the MAF. Don't know if that is the problem. Where is your wideband iput? Your map should read 100kpa at key on engine off. Looks like it reads 50 ??

Agree with Lakegoat. In addition what MAP sensor are you running? Looks like your scanner setup is still at 1bar. May also need to change Min Fuel Milligrams in Transient Tab to a lower number with those injectors.
Thanks for the replies....I am new to this...LOL... I will follow up on what you have posted. Thanks again..
