I think the issue with it is that the blowers and N2O kits gneerally
work by boosting (significantly) the fuel pressure, and that is how
they get more fuel into the engine, and the gage apparently does not
respond fast enough to this boosting of the fuel pressure.  I think
stock the f-bodies run 45 psi, and I have heard of the kits boosting
the pressure up to 60psi or more, and this is all at the same rate as
the rpm is rising (for a blower).    It may be less of a problem in a
N2O car since it should only boost once, and then stay steady, where
in the blower the pressure is rising at a fairly rapid rate, with rpm
(rising boost).
