Mustang Mk.III is just an RAF version of the P-51B/C. However the RAF converted some Mk.III's to run on 150 octane fuel (normal was 130 octane fuel), which gave a sea level top speed of 390mph (compared to 360mph normal). Speed at altitude remains similar but the boosted 'Stangs were very successful in RAF sevice, both in shooting down V-1s and also intercepting low level raiders, and once the V-1 threat had been resolved they were very successful against other German aircraft.
The Mustang Mk.III in Il2 1946 is the 150 octane version.
Other aircraft to benefit from 150 octane fuel improving their low altitude performance were the Spitfire IX/XVI(335-358mph at sea level), the Griffon engined Spitfire XIV(359-366mph), and the Tempest V(372-386mph).
