This would come up when the tune was trying to maximize the mpg. I have never tried to correct this with out live tuning and map tracing, I imagine it’s a pain
This was my original concern. However I have since switched to running dimemod patch which I didn’t even know existed up until a couple of weeks ago. Since switching to dimemod the car is running full speed density with iat still in the maf and so far idle is mint once warm. It hunts a little when warming up when the coolant is cold so I need to address warmup enrichment after VE is fully scaled which it nearly is. By the way this dimemod patch has insane features! It has:

Launch control that can be set to fuel cut or ignition cut or a mix of both.

Auto rev match

Rolling launch

Antilag

It has capability of controlling methanol injection

Map switching

Hybrid maf/speed density

Full flexfuel capable

All on a stock ecu. It does cost money but in my opinion still worth it and you still use ecuflash to edit the map as well as romraider logger to log. For those interested definitely worth checking out. As for why the car hunted idle and stalled on merp mod I have no clue. I ran smilar VE values down low but for some reason the car would just not behave.
