What exactly does the MAP sensor do for a 03/04 Cobra?

[QUOTE="PistolWhip, post: 7182869, member: 30361"] No, it uses the FRPS and MAF to calculate fuel delivery. The only reason I'm asking this is because my Aeroforce gauge is only reading 15.6 PSI and that's constant, no fluctuation at all, at WOT. The factory boost gauge reads almost 18 PSI at WOT. I'm running a GenII Whipple with a 3.10" pulley, so 18 PSI is more realistic than 15.6. I was thinking maybe the 15.6 was maxing the MAP sensor and that's why the gauge was only reading that high. Usually you will see at least a fluctuation of .1 or .2 in either direction on a WOT pull as you go up the RPM scale and I'm not getting that at all. [/QUOTE]
