2005 Mustang GT turbo stock MAF in blow through

[VeryCoolParts.com]

I have a 2005 Mustang GT with a forged shortblock, 76mm turbo, intercooler, and right now it's making 447 RWHP at 5000 rpm where the meter pegs at 4.99 V. The MAF is stock 05 electronics blow through in a 2.8" ID section of tubing with 8" of straight section in front of it. It will make about 500 RWHP at the current 8 lbs of boost. What HP level is each setting on the MAFia?

Seperate question: How does the ECU calculate the load %?

Load calculations will need to be adjusted by the air mass displacement in the tune. But fueling changes will need to be done based on the setting the mafia is set to. Setting 2 will most likely be the setting you will need it on BUT you will need the tune changed for the mafia.

Cole, I had to go with setting 3 as the MAF tube is really too small. It also made 614 RWHP at 17lbs of boost...

Yes smaller tubing will eat up more of the meter voltage.
