manifold abs. pressur . 1 bar senser is good for up to 14.9 psi ambian air pressur is 14.7 on a normal day if you max that out intheary you flat line--------------------- so you go to a 3 bar wich is good for 29psi . maybe (bar) is a maine term sorry1994 Z28 stage 2 intercooled procharger, P-1sc, 6lb pully,42lbfuel injectors,255intank pump,1 3/4headers,highflow cat, borla ajust. cat back,chrome moly LCA,chrome moly ajust. panhard bar, Kenny Brownweld-in subframe conectors, built trans. kevlar lined 2600 stall, kevlar clutches, hardend parts,,built rearend; moser axles, eaton posi, richmond 3.42 gears, rare ROH ZR6 17* 9.5 wheels, custom computer tune with laptop and LT1edit , 380rwhp 395rwtq , 60' 1.71, 1/8th 8.00,1/412.60@109mphComment

A 3 bar MAP sensor is good for in excess of 43.5 PSI. Normally for 10lbs of boost or less your stock MAP sensor should work fine as long as you are not switching to a speed density setup.
But if you want better logging and tuning abilities most of the guys use the MAP sensor that came on the late 80's turbo TA's. Part # 12223861. You will also have to use an adapter connector. Not sure of that part# though.Comment

The answer depends on how you add the extra fuel required by the boost. If you are using an FMU, the fuel control is external to the PCM, and there is no reason to change the MAP sensor. You could log the MAP voltage using a scanner, but you would need to have the calibration table of sensor volts vs. kPa.
If you have had your PCM reprogrammed to provide the extra fuel, the tuner has already accounted for the fact that he is limited to the data that the 1 bar (14.5psi, 100kPa) sensor provides. Changing to a 2 bar (29.0psi, 200kPa) or 3 bar (43.5psi, 300kPa) sensor would simply require that he redo the tuning based on the new MAP sensor signal.
How do you add the fuel to your system? What boost level are you running? Are you running the stock PCM? Who otuned it?Fred
