It's a little more complicated than that.
Because lightnings are supercharged their IAT sensors are seperate from their MAFs.
I have a IAT sensor in the intake at #1 runner. This gives a more accurate IAT reading. You have to remove the IAT sensor wires out of our oem maf and run them to the lightning IAT sensor.....where ever you put it.
Than you can install a lightning maf in place of the oem maf.
I got my lightning maf and IAT sensor from Ford oem parts dealer.
Note the bigger TB will flow more air than a stock TB once the opening matches the stock TB max opening. So if aftermarket TB is 5% bigger than the last 5% will add more air than stock.
If you don't have a custom tune you cannot use a lightning maf. Stock iat sensors read ambiant and pcm increases iat in pcm by 30 to 50 degrees. So a stock pcm or KB chip will increase all iat sensor readings and mess up volume readings for AF ratios.

If you have a 4 wire maf and 2 wires going to the seperate IAT sensor you are good to go.
The lightning maf has 4 wires.
Be advised that since the lightning maf is bigger it will need to be calibrated in the pcm logic.....IE tuned.

Like a sewing machine.
Had to switch to a 2004 F150 Harley Lightning fuel pressure regulator. It fits in factory regulator hole.
V10 unit went kapoot as I don't think it could handle 12 psi boost.

no it can only hold 10 pounds of boost with sparkplug fixed and water methanol injection mine runs like a raped ape
