Ambient temp was recorded as 28 degree Celsius for the M2C vs 9 degree Celsius for the M2. The S55 didn't get the same air density as the N55 during the trail as cooler air increases air density thus more oxygen which means more power. The S55 was at a disadvantage.
On the same day with both cars running the M2C will clock faster time for sure.

Sport Auto likes to run those MPSS super low, like 2.2 bar warm, for a street tire that is just too low and speaking from experience, those pressure are killing those super soft MPSS sidewalls, i even spoke to a lot of "specialists" around the ring regarding tire pressure(s) on street tires, they all seem to agree with this.
They even recommended running 2.0 rear and 2.5 bar front on NOS when warm, still far too low for those tires.
I did not finish reading the article, but i'm interested to find out how much pressure they ran on both cars on NOS and Hockenheim Short.
My point is, even at higher temperatures, tire pressure can be adjusted to provide close results. The more concern is the intercooler/turbocharger getting heated up more on higher temps than probably a tad more power in lower.
