Again, I am no Spitfire expert, so correct me if I am wrong, but isn't the real world +6 lbs. Spitfire using 87 octane? If so, shouldn't the in-game 100 octane (i.e. +12 lbs.) version be faster that the +6 lbs. below the FTH?

Perhaps I am not understanding the question fully, but all Spit Ia's at +6.25psi boost (full throttle) should go the same speed whether they are using 87 or 100 octane. The Spit 1a 100 octane has the ability to use +12psi (using the modified boost cutout red tab) and go faster (provided it is below FTH for +12psi). There is an intermediate altitude range where the supercharger can give less than +12psi but more than +6 psi, above that 87 and 100 octane variants are equal.

I assume your flight tests for the CoD Spit 1a 100 octane were using the +12psi boost? Did the engine blow up during tests?
