Kenne Bell 168mm voltage issue

Hello guys. Dodge challenger 2008 srt8 +kenne bell 3.6lc, azn cam.
Issue we have that lowest we can go with 0.04V on throttle body, and if jump lower voltage car goes into limp mode and half cylinders gone(red thunder bolt shows off), need to restart engine. We need to try 0.02 or 0.03 voltage to check if we can lower rpm with that massive TB. check engine lights we disable because of low voltage, but how to disable that limp mode?lowest rpm we can get now at idle is approx 1100rpm and about 17 afr. Maybe there are another options?? Appretiate

Probably gonna have to modify the tbody to close it more while getting the tps voltage up a few more tenths. or you have a vacuum leak somewhere.

My 168mm idled perfectly at 0.12 to 0.15 volts opening.

Check for vacuum leaks, that is a REALLY tight opening you are trying to accomplish, motor should need more than that unless there is a leak

Did you try lowering minimum desireed throttle opening table 3520? In my factory tune it's set to 0.04. The mopar crate PCM shows 0.00.
