Spitfire supposed to dive better than the 109?

[whoarmongar]

Clostermann and his wingman Ian Blair in Spitfire VII`s (high altitude presure cabins extended wingtips) intercepted a german aircraft that Clostermann reported as a Me 109G with aux fuel tanks under the wings at 43000 ft.
Faced with two Spits ahead and about 1000 ft above him the 109 rolled onto his back and dived straight towards the sea, with the Spits about 1/2 mile behind and following him straight down.
At 27000 ft Closters A.S indicator showed 440 mph and he needed both hands on the stick and to lean into the controls with all his strength to keep the aircraft in a straight line.
The controls were jammed @10000 ft Ian Blair closed to within 600 yds of the !09 and opened fire a short burst. The Me109G tore in half a wing tore off and the aircraft exploded.
Pulling back on the stick wasnt pulling the Spit out of its dive so he gave the trimmer a full turn back , the G force crumpled him, the whole aircraft creaked and groaned and the momentum had carried him up to 13000 feet.
