Is the MAF before or after turbo on SR20? if before then how can the MAF know how much air is going in to the engine if I turn up the boost more than stock? Also if it is before the turbo how can it be out flow because if at wot it can only take in x amount of air but the tubo compress that air and get more power so no matter how many boost i m running and the maf is before the turbo the maf whould not max out is that true ? ---

the maf goes on your air intake hose coming off your throttle i believe it measures the air coming through the intake into the throttle. Correct me if im wrong but i do believe. ---

turbo has to suck as much air as it blows out as long as all the air that goes into the turbo goes through the maf first it doesnt matter ---

maf goes right after the filter, the BOV should be resirculated the ECU needs the recirc for its program… otherwise metered air (through the MAFS) is lost to atmosphere, then it goes rich and bogs unless you’ve tuned around it if your just doing the SR swap the wiring harness must be lengthened to reach the MAFS position ---
