But like I said, it is near impossible to get a good tune with because of the inconsistancy of the fmu. It would be ideal to buy properly sized injectors for the application, ditch the fmu and hack into the ecm for proper tuning. In the article they aren't doing any tuning. They're just bolting crap on and hoping to trick the ecm. A "calibrated" maf isn't needed if you install the proper transfer function in the tune. Also tuning a car with "big" injectors isn't a problem if the tuner knows wtf he is doing. Good luck</p></blockquote><p></p>
