e38 idle and off idle is kicking my a**
edit: be sure to read post two as i have an update
first ill give the issue, then the details or the setup, and last ill be smart and post my last log and tune file to skip being told to post it up.
As i depress the throttle slowly the motor will drop in RPM in park, in gear it will stall. If i dont baby it and push it quicker but still on the conservative side it will rev just fine so its ONLY a light throttle stall/stumble when going from 0% to say 5% accelerator pedal position. I was having the issue in park also but managed to eliminate it by increasing the airflow minimum table. Still has a slight surge when coming back to idle but not bad enought to push through the converter. I have referenced LS7 and the GM crate 525 LS3 tables and I'm well above them both now. Startup I have dialed and it lights off immediately.
If it was a Gen3 setup id be good i believe, this is my first Gen4 with a cam swap so I'm still learning the specific tables and getting frustrated
