**If the car was going to see a decent amount of track time, an upgraded suspension & LSD would get added to the list.
While none of the tunes require oil coolers or FMICs, they should be added/upgraded if you want consistent & safe
performance gains. Like I said, the oil cooler isn't a required part, but there's a reason why after 08 every N54 car received one (and that the 335is & 1M both receive upgraded cooling components) from the factory.
The OP can try moddin the car without adding the oil cooler, but I can't promise if the quality of the oil will be compromised over time & that the car won't go into "Limp Mode" after some aggressive driving.
I may be the minority but I fail to see the big deal with an upgraded FMIC for a DD car... I see it as an important part if you are consistently tracking your car or if you are driving around in hot weather all the time. We are currently approaching winter and for most people this mod will do next to nothing... its a dyno day / track day mod more than a daily driver mod... I would do DPs long before FMIC but that is purely my opinion. I saw the same situation on any other platform I've owned or worked on...
