it doesnt matter supercharger or turbo, the MAF maxes about 13 psi, and the stock MAP sensor is only a 1 bar, which measures vacumm, no positive pressure (boost) so at a minumum you will need to rescale the MAP tables with some tuning program and run a 2 Bar map...do a search on that for more info...
or you can be cool like me and run a megasquirt
realtime tuning of ignition and fuel, wideband compatible, boost sensitive to 21 PSI
