ok cool, sounds like you have some idea. out of interest what car and engine is this going to be on?

the reason you cant use the standard engine management is because its not been mapped to run boost. for any given engine map there is scope for a few mods like zorst and induction kit but any more and the ecu cant compensate for the increase in air and it'll run lean and melt a piston very fast! i suppose you could get around this by running bigger injectors and uprated fuel pump but it still would be way off for on boost and would certainly be wayy off for off boost so it wouldnt run right at any time.

not to mention yiu will prob exceed the maf's measuring limit as it was designed for a n/a engine.
