      Product Information

      Features, Description, Reviews, Q&A, Specs & Installation


      • No More "Pegging"
      • Eight Settings for all Horsepower Ranges
      • Supports up to 800 Horsepower
      • Plug and Play - No Cutting Required
      • Works with Stock and Aftermarket Mass Air Flow Sensors
      • Fits all 1996 to 2004 Mustangs


      No More Pegging. The Diablosport "MAFia" MAF Interface Adapter is perfect for applications where the stock mass air meter "pegs" due to increased air flow. When the MAF sensor reaches 5 volts, it "pegs the meter" maxing out the signal, preventing you from making peak horse power at higher RPMs, but the MAFia extends this signal allowing your Mustang to make up to 800 RWHP without "pegging the meter".

      Settings. Featuring eight preset settings, the Diablosport "MAFia" MAF Interface Adapter is perfect for all horsepower ranges, from street/strip car calibrations all the way up to 800 plus horsepower race cars.

      Tune Required Settings. Settings 2 through 6 on the MAFia modulate the signal from the MAF to the computer to a point where a tune is required to properly allow these changes to be applied to the computer. Settings 0, 1 and 7 modulate the signal from the MAF to the computer, but not to the point where a  tune is required.

      Application. The Diablosport MAFia Mass Air Flow Calibrator is a direct plug and play upgrade adapter for all 1996 to 2004 Mustangs, including the V6 GT, Bullitt, Mach 1 and SVT Cobra models with either a factory or aftermarket MAF sensor.

        Works well

        The only thing I could say is don’t buy this product unless you plan to tune your car by a professional, although it has decent preload features

        5 2001 GT - ClintB Installation Time: Less than 1 Hour

        Just what I needed - MAFia

        I recently installed a Procharger P1SC on my 01 Bullitt and had to have it tuned. According to procharger, the stock maf would handle the horsepower I was expected to make, but it couldnt. Similar replacement MAFs are in the $300 range and I didnt want to spend that kind of money. The tuner suggested the Diablosport MAFia to me, and it worked perfect. He set it to a 30 setting and I ended up at 375 hp and 385 tq at the tires. Very happy with the diablosport MAFia.

        Does what it says it'll do!

        The MAFia does exactly what it says it does! Car runs MUCH better now! My only complaint is that the wiring harness could be 6 inches longer. My MAF is now inside my fender well so longer wires could help me locate it in a more convenient location. Otherwise it's a great product.

      So, this is only for supercharged/turbocharged Mustangs, right? No effects whatsoever on cars with only a CAI?

      • Hey Ali, Its not just for any type of forced induction but its a sensor that can handle up to 800hp. The only thing is that you would just need it tuned to your mustang. So it can work with just your CAI.

      Will this work with my set-up? I have a NA 4.6L V8 with a BBK 78mm throttle body, K&N cold air intake with a stock MAFS on a SOHC rebuilt engine producing 400hp. It "hunts" for an idle on occasion and I think it's getting too much air for the stock MAFS. Will your MAFia address this problem and what setting do you think I should use? Thanks, White Eagle

      • The Diablosport MAFia is a mass air extender, meaning it gives a larger range of useability when the current MAF has exceeded the limits of its airflow metering capabilities. Unless you have exceeded the limits, there is no need to use this product on your specific application.

      I have a v6 3.8litres with a procharger I have a lot of problem with the mix to proclaim mo says that the air mass flow is at the maximum reading can I put this to solve the trouble

      • This will extend the range of your factory MAF, you will need to tune for this as well with your application.

      I have a 2001 v6 turbo car will this allow for the correct airflow through my stock maf

      • Unfortunately, the Diablosport MAFia will not be able to correct the airflow. We recommend if your running force induction parts on your vehicle to get a dyno tune.

      I have a 2004 GT... Will this be plug and play or will I still need to add an external IAT sensor like all the others? Thanks

      • The Diablosport MAFia is plug and play!
