So speaking with SCT (Derive) a while back, they didn't have much of an answer for a value file for my 05+ Slot Style MAF in a gt500 112mm housing. What they did tell me was to use the BA5000/4inch value file and go from there. 112mm is close to 4.5" so multiply 4 and 4.5 by pi for your surface areas, divide for the difference, .8888 x MAF table, Fuel injector Breakpoint, Manifold Volume, Engine Displacement and Fuel Injector Slopes. This got me really close! Just a little fine tuning with a couple of widebands and this mother rips!
Here's a wiring diagram below for the conversion.
Or you can just by a conversion cable:
