You use it to add headroom tothe MAF voltage by adjusting the inner dial from setting #2 and up. Use the lowest setting where the MAF willnot peg. It installs between the MAF and MAF connector. And... you DO need a tune to get it to work - it is NOT plug and play...

i also have a diablosport tuner, so i do have a tune, i have the stock 19 lb injectors, i want to move up to 24's, what setting would i need to set the mafia to to calibrate to 24 lb injectors?
What he maens is the tune has to include the mafia in your tune set up. Who ever made the tune for your diablo will have to make adjustments to it to include the mafia.
Why are you trying to use it. If you are only using 19's, you aren't pegging the MAF, so there is no need for it. What makes you think you need the 24's also?
tha mafia isnt for calibrating to new sized injectors, its for when your MAF is pegging out (motor sucking in more air than the MAF is designed to properly meter)
not sure what year car you have but a tune would easily allow you to run 24lb injectors with no issues.
how do you know if the 19s arent enough , what mods do you have ? give a complete run down of what is on the car and where did you get the diablo from and who did you get the MAFIA from because you cant just hook them up and expect it to work , you have to have a custom tune for the MAFIA loaded up on the diablo flasher with a different transfer function loaded in , you also need to change about 4 other things in the tune for adjust for the 24 lbs injectors
Sounds like you need a new tune to calibrate for those larger injectors. What mass air meter are you using now? If it is stock, then you might want to look at getting a lightning 90mm mass air. I am unsure of what mods you have, or how much power your putting down, but it wasn't until I made 400 HP at wheels that I pegged the lightning mass air meter. Now I have the BA 2400 from SCT, and it has not pegged yet.
i have stage 2 patriot performance heads, and .550 lift 237 duration cams, long tube headers, x-pipe, aluminum pulleys, diablosport programmer, and the mafia that im trying to get working, the MAF is stock and the injectors are stock.
