As I stated in the previous post, it would be quite weird for someone who doesn't play the game to want it changed. That's why I asked.
AFAIK, several units with a total of at least 142 aircraft (79 serviceable) used the 1.98 ata manifold pressure operationally. You can find the full list here:

Galland instructed 109 ground crews to set the maximum ata to 1.98 in 1944. You can find the original orders in that same link.
If you read from anyone that is not Kurfurst, whose nonsense is continually debunked, his assumption about those units is just that: an assumption. There is actually an entire thread about this on this very forum, as well as many others. There is no definitive evidence of the operational use of 1.98ata.
Once again well end of February....: Messerschmitt's Erprobungsbericht Nr. 15 vom 16.1.45 bis 15.2.45 dated 22.2.45 states that 1.98 ata is blocked, testing done at 1.80 ata: WM 50 Betreib - Nach Mitteilung der E'Stelle sind 1,98 ata gesperrt. Die Erprobung (Funktion und Kerzentemperatur) wird vorläufig mit 1,80 ata (2800 U/min) durchgeführt. 40
There is a very good reason that Mr. Kurfurst is a "parolee" on these forums. He was also banned from ww2 aircraft forums and is well on his way to being banished from the DCS forums.
