Why´s that? For the easy reason the XIV while in fact very fast, was already suffering a deteriorating handling.

Have you read the ADFU tactical trials of the Spitfire XIV?
Strangely enough, they performed a DIRECT comparison to the Spitfire IX.
Here is what they found;
**************************
ADFU Report. 117 16th June 1944
TACTICAL COMPARISON WITH SPITFIRE IX
13. The tactical differences are caused chiefly by the fact that the Spitfire XIV has an engine of greater capacity and is the heavier aircraft (weighing 8,400 lbs. against 7,480 lbs. of Spitfire IX).
Range & Endurance
14. The Spitfire XIV, without a long-range tank, carries 110 gallons of fuel and 9 gallons of oil. When handled similarily, the Spitfire XIV uses fuel at about 1 1/4 times the rate of the Spitfire IX. Its endurance is therefore slightly less. Owing to its higher speed for corresponding engine settings, its range is about equal. For the same reasons, extra fuel carried in a long-range tank keeps its range about equal to that of the Spitfire IX, its endurance being slightly less.
Speeds
15. At all heights the Spitfire XIV is 30-35 mph faster in level flight. The best performance heights are similar, being just below 15,000 and between 25,000 and 32,000 ft.
Climb
16. The Spitfire XIV has a slightly better maximum climb than the Spitfire IX, having the best maximum rate of climb yet seen at this Unit. In the zoom climb the Spitfire XIV gains slightly all the way, especially if full throttle is used in the climb.
Dive
17. The Spitfire XIV will pull away from the Spitfire IX in a dive.
Turning Circle
18. The turning circles of both aircraft are identical. The Spitfire XIV appears to turn slightly better to port than it does to starbord. The warning of an approaching high speed stall is less pronounced in the case of the Spitfire Mk XIV.
Rate of Roll
19. Rate of roll is very much the same.
Search View and Rear View
20. The search view from the pilot's cockpit is good; the longer nose of the aircraft interferes with the all-round visibility, which remains the same as that of the Spitfire IX. Rear View is similar.
Sighting View and Fire Power
21. The sighting view is slightly better being 4 deg (140 m.p.h.) as against 3 1/3 deg. The two bulges at the side cause little restriction. The firepower is identical with the Spitfire IX.
Armour
22. As for the Spitfire IX
Conclusions
23. The all-round performance of the Spitfire XIV is better than the Spitfire IX at all heights. In level flight it is 25-35 m.p.h. faster and has a correspondingly greater rate of climb. Its manoeuvrability is as good as a Spitfire IX. It is easy to fly but should be handled with care when taxying and taking off.
END OF SECTION
*********************
The ADFU, who tested all RAF planes for combat during the war, concluded that the turning circles of the XIV and the XI were identical, the XIV turned to the left better than to the right and that the stall warning was less pronnounced than in the XI. I hardly think this qualifies the XIV as having "deteroiated handling"
Another section from the same report;
***********************
FLYING CHARACTERISTICS
5. In most respects this aircraft is similar to the Spitfire IX, except for some very marked changes in trim with alteration of throttle setting below 0 boost. This applies principally to the rudder, despite the incorporation of the servo-operated trimming tab. This is the one bad characteristic of this aircraft. The elevators also require more frequent trimming than in a Spitfire IX.
