greetings all
we have this car tuned already a month ago and P2173 issue was major. Now, I have tuned it and this issue is still there but less happening. Still I want to fix it once and for all. The car is challenger V6 8speed 2018 with sprintex supercharger. As you all know, this code cause sudden engine switch off while driving.

Not sure if this is your problem, but your peak airflow under engine diag/airflow (table ECM 14064) appear to be stock. I have seen them bumped up on other tunes (like in the one in the link below - also happens to be a FI 2017 3.6).

Also try enabling sensed MAP

That table of the airflow was tuned but no results and I guess I need to max it outQuote:

I dont seem to have any leaks. I am also shutting down on WOT or a hard throttle push. Like i loose boost. We r still in the tuning stages.
try increasing the adapt under engine diag it has the same codeQuote:

Have you enabled sensed MAP?Quote:
