If the overboost came with the correct penalties (high probability of engine damage when overused) for Spit and 109 the problem wouldn't be one.
If everybody was forced to conserve his engine and to keep it well in the green, the peak power would heavily loose in importance, as it would only be advisable to use in emergency or in a chase with air superiority.
Even then, as further away from home as less advisable would be the use of WEP.
Regretfully CoD is still missing a lot in the CEM-part to make this workable.
To give the power now, as it is would give all advantages to the spits, turn and speed, very unrealistic.
Imo, of course
