Current engine performance correction standard : 80/1269/eec.
The reference ambient conditions are 24.85 deg. C,  99 KPa (990 mbar)
Power correction is Po = a.P  where a is the correction factor and P is measured power
Correction factor    a= (99/p)^1.2*(t/298)^0.6
p = dry atmospheric pressure (kPa) = total barometric pressure - water vapour pressure
t = atmospheric temperature K
Correction based on 10'C temperature drop alone without pressure compensation

Therefore pressure boost @ 120mph in mbar@2542mv = 11.59mbar
Mbar boost calculated from gradient of MAP sensor Voltage/pressure = (Volts*gradient+Constant)	1011.59362
11.59*0.014=0.1622psi
