Im plowing through a 3rd party campaign right now (WWII Cruise part 1) and my AI wingman don't use the multi stage supercharger. Our aircrafts are F4F-4. I switch to the 2nd stage at 8,000-ish feet, like I am supposed to, and I instantly start pulling away from my fellow team mates. They can never catch up unless I throttle back to like 70% (manifold pressure bellow 40)

Is it like this for everyone or is it just me?
What can I do to fix this up?

Thanks you very much in advance

The AI are probably flying at the preset speed; usually about 300 kph. They SHOULD stay with you if you are the flight leader, but they will ignore you if you are not.

The AI has a simplified flight model and it generally is more effecient than your flight model. They probably don't have a true supercharger setting like you do. In general, you should stick with them, even slowing down if you have to.

AI-only planes have a simplified FM....
