Re: Evo X upgrades
There is no reason the MAF shouldn't max in a housing close to stock size. Mitsu wouldn't put some crazy oversized setup on the car. With a hotwire setup you want the MAF diameter to be somewhat close to what you need, the bigger you go the worse driveability gets and less resolution you have in the low throttle areas where you need it. All the Mustang, Subaru, Nissan, Audi, etc guys goto bigger MAF housing/pipes when they make more and more power, it isn't anything weird or new. For the Mustangs you can buy calibrated MAFs with flowsheets and the numbers that you need to plug into the MAF scaling tables in the ECU to make it easier to tune.
Also remember that someone might not notice the MAF is maxed and just try to over compensate for it by adding fuel to the main fuel table.
