Hello everyone i need a little help please. my set up is 2018 5.0 (gen 3) with Roush 2650 supercharger. i have been running with ghost cam tune, deleted cats and has been running great until i installed Stainless works Long Tubes no cats. my fuel trims and Lambda is on point while driving But when stopping and at idle it now surges bad. i have added .050 to the transport delay tables and added to intake ghost cam table to try and smooth things out. After putting 50 or so miles still not idling great. this is a good tune that i have worked on for 2 years now. lol feel free to copy.

On my car I needed to go into the mapped point that was used for idle and bump the torque up just a bit. didnt take much at all. This made the torque request command just a bit less load, which calmed it down and allowed the engine to idle pretty well just using fast path control (spark).
