In reality most Spitfire Mk XVIs ran at +25lbs boost, but the one in AH runs at +18lbs boost. How far should this sort of thing be taken?
What you are asking for is exactly like asking for a Spitfire LF.Mk IXe at +18lbs boost and a Spitfire Mk XVI at +25lbs boost. Same aircraft with different names and different boost settings.
