Features & Details

  • No More "Pegging"
  • Eight Custom 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 2005 to 2010 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".

Custom Settings. Featuring eight preset custom 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 custom 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 custom tune is required. Please contact one of our Bama Tuning Specialists for help in determining your specific needs.

Application. The Diablosport MAFia Mass Air Flow Calibrator is a direct plug and play upgrade adapter for all 2005 to 2010 Mustangs, including the V6, GT, Bullitt and Shelby GT500 models with either a factory or aftermarket MAF sensor.

I have a 2006 V6 With a turbo and nitrous to reach 400-450hp and im having trouble deciding between this Diablo MAFia and the SCT Big Air one. The big air requires a dyno tune to fully benefit from it, but this one doesnt say that. 1.) What would be the key differences between this Diablo MAFia one and the SCT Big Air? 2.) And why does this MAF not require a Dyno Tune?


Can I use this? I have a m122 supercharger that i custom installed on my 4.0 mustang. But my stock Mass air meter is maxing out at 4700 RPMS. Can i use this instead of buying a new mass air meter? thanks


  • Yes, this will work to extend the range of the MAF sensor. After installing this the tune will need to be updated to accommodate for how this re-scales the MAF though.

Will I Need this? I am fixing to buy a ford racing cold air intake for my 2006 v6 mustang. I know a tune is required for the air intake because of how much larger the air intake is but will i also need this to get the most out of that air intake and the most hp out of my car?


  • You should not need this MAFia unit for your Mustang. This device is intended for Mustangs adding a supercharger or turbocharger where the factory sensor may not be reading the amount of incoming air properly. The MAFia unit allows it to have a wider range to monitor the incoming airflow. So, with you being Naturally Aspirated currently this wouldn't be needed.

Can this be used with CAI? Put a CAI on my v6 but had to remove it because it was runnin lean can this replace doing a tune?


  • No, you will still need a tune for your cold air. The MAFia can only richen the MAF curve by 5% without a tune and typically that is not enough with a Cold Air kit.

Pegging i do make over 400 HP at the wheel i have a saleen superchager with super shaker set up pushing 500HP does this mean i need a new MAF meter or a MAFia what if i dont have the tunner do i need to buy that too.


  • This mafia will definitely work for your car. However we can't write tunes for this item. We highly recommend getting the car on the Dyno to dial everything in perfectly. If you have further questions, Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 10AM-3PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!

What is this What is pegging? What will this do to my 07 stang


  • A MAFia is used when you have too much horsepower for your MAF sensor. The volume of air passing the MAF is too much for it to read, so it flat-lines at the maximum voltage reading. What this product does is trick the MAF into reading higher, and extends the hp range that you can get away with using your MAF sensor. On your 2007 Mustang, it's not going to be necessary until you're running a superchager, and even then it depends on what size inlet your factory MAF sensor is placed in. You'll probably be a good candidate for this product if you're making over 400 horsepower to the wheels with your factory MAF sensor. Hope this helps!

    Diablosport MAF Interface Adapter

    Really works. Faster acceleration. For those of you that think their mass air is pegging, you need this.
