For my mental state it sure is. The downside is a reduction in income of about 25% for the remainder of my working life (about 12 years to go until retirement) which will also significantly impact my retirement funds. That is a lump that is hard to swallow...

Dang... I forgot about that... Indeed, that pump now works with colder air which has different compresability.
Remember that you mentioned "lots of power"? make no mistake, the engine actually IS developing more power in winter because of not only the larger quantity of air ingested, but also because of its compressibility.
I distinctly remember that on the big ships when in colder climated, we were required to reduce power a bit, not because of the engine, but because of overloading the turbochargers, that had difficulties (WRT material strength of the blower wheel) in too cold and too dense air.

I am sure it has an effect, but since I forgot about your air pump, I am now unsure which effect is greater.
Regardless of which, they most likely still follow temperature and should be or could be compensated for in the formula.

Yeah, I am most definitely convinced that what we have here (the electronic addition by means of solenoid valve) is way better than anything analog out there, because just as an example, my trusty old Ducati cannot handle the ambient airtemperature range that my "ex-glow engines" can...
That bike needs an intake air preheater to run right in colder temperatures, that no one fits because it is such an extreme hassle to fit it and remove it again in summer....
