Climbing at such a reduced airspeed will limit the cooling of the engine at a very high manifold pressure and rpm.
If your oil temperature and coolant temperatures are high, you won't last as long at any overboosted condition.
Try climbing at the faster speed. You should get to altitude quicker and have a cooler engine.

True for a real MkI, but remember we are talking about a CloD Spitfire with modelling issues.
I tried climbing at 170mph IAS to 16500ft, +6.2psi 2700 rpm
Oil temp at 16500 feet 93'C, coolant 107'C

Throttle back to +2psi 5 mins for cooling, Oil 91'C, coolant 100'C
Then 3000rpm +6.2psi for max speed test.

What do you get under similar conditions? I don't want to give away all the flight tests, we need to encourage a cadre of high alt flight testers for CloD to get some data variability
