True, but the P51D is still heavier than a Spitfire, even the Griffon powered Mk XIV, and it gains its high speed through good aerodynamics and a laminar flow wing, not a high power-to-weight ratio.
Higher weight and a smaller wing area means the P51 cannot turn with a Spitfire, but its turning circle is marginally better than the German Bf109G and the Fw190, and its high speed roll rate and instantaneous turn are much better than the Bf109. This means the P51s manoeuvrability, while not outstanding, is sufficiently good to take on German fighters, unlike the P38 and P47 which were built around American air force specifications calling for heavy long range fighters.
