Rolls I have been suffering from this exact issue! I think last time we spoke about it you described it as similar to towing a trailer and then the car just releases it.
It's been shitting me so much because sometimes driving on the highway in the morning I can feel it swapping between the two and my car just goes gutless then back up and gutless again.
Makes it really annoying driving in the mornings in ACT
Also it's exactly as you described with the 1min before it swaps to the map. I'll be cruising out of my street and then boom the car goes sluggish.
Does it have any relation to RPM because I find it feels a little less like a slug when I slowly bring it to 2500-3000rpm it frees up again
