Serpents Head Part 1 issues

Hi all,

I have some issues with this campaign that I have no idea whats up

On mission 1, My HUD Airspeed is showing KIAS (which I understand) but this means that when I get to the needed 350knts to keep pace my hud sits at around 220ish and I have ti use the HSI to monitor ground speed. In this video (credit to Davis simulation gaming) thier hud shows correct speed. It makes it really difficult to monitor air speed

Next, my throttle doesnt seem to line up with the ingame throttle. I have my detents set in VPC configuration tool and in free flight and other campaigns, its fine but in serpents head mission 1, my full mil power has the IFEI sitting around 92%, I have ti use AB sometimes to cath up to formation because full mil isnt enough.

Has anyone seen these issues before please? Any help will be very much appreciated, Im pulling what little hair I have out
