Spit has only 2 prop pitch settings and carburettor engine while 109 has fuel injections so has no fuel flow stops during high G's.

Your figures listed for the Spitfire are for +6 boost 1030hp versions, when in fact, nearly all the Spitfires operational in the BoB after July were using +12 boost.

I would suggest you look through this page for the details re. the evolution of Spit I performance:
