First I MUST MUST agree this is a very brilliant thought!
Meanwhile I have a little doubt here:

When I use MCB or any other way to increase boost, the PCM will know the current REAL temperature and the boost it's having, therefore PCM can delivery sufficient amount of boost (assume you have to correct fuel mods)

When I use the fake intake temperature mod. PCM will assume current temperature is 120-140F. So I guess it will just increase boost without increase fuel, since higher temperature gives you less dense air -> less oxygen.

Overall, I am gussing the difference here is other boost mods will not fool the PCM at least, then right amount of fuel can be injected. Here PCM "may" not giving more fuel even though the boost is increased, since it's "much hotter".

However I do agree factory fuel system runs very rich, but my point here is that if you see 15psi when you do this mod, it may not be exactly the same as 15psi via other boost mods.

I am not a professional in car systems, here is only my thoughts. I will be very much appreciated if someone can correct me on this.
