So this is a MAF housing I made, and hopefully it works out well. It's to adapt 2.75" charge piping to 3.25" to 3.5", then back down again. It's a piece of 3.5" exhaust pipe necked down to 3.25" then a pair of 2.75" to 3.25" couplers I got from Velocity Racing. Right now I'm dailying the Eclipse while the TT gets a new clutch. I should be able to get this in there in the next few days depending on my work schedule. With it, I should be able to up my boost to whatever my turbo is willing to feed the motor. Hoping to break 500lb-ft torque, but probably won't break 500hp. It'll be somewhere around there though. Exhaust flow is what's gonna limit my horsepower. It needs external wastegates

Housing is in, and from the 121mm scaling I'm at 250mm now. AFR are pretty close, but I've got some fine tuning to do. It idles great, but is a touch lean at full boost.

No more lean (13.5:1) under boost, but I've still got tuning to do. My STFT bounce around a lot at idle from -10 to +10, and at cruise it's 15-15.5:1 and -20stft.
MAF voltages were 4.8v at 12psi 7800rpm, and now are 3.9v at 14psi 7800rpm.
I also am playing with off throttle pops. The car is sounding pretty wild off throttle now
