hi if i get an ecu for my uno turbo, bosh type that has been re mapped would this give me increased revs and bar or does this just mean it has been cleared of any flat spots? the reason i ask is that ive been told you cant do anything to the ecu on turbos as all tune up work is done on the air flow meter?. if some one could send me or post a little explanation id be very gratefull. thanks.
