Also an advantage to running the MAF right before the intake mani is if you have a boost leak anywhere before it or if your coupler blows off your intercooler your car will still run fine. Although a side effect of it would be you wouldnt be able to tell if something was wrong like a boost leak unless you do a leak test or have a vacuum gauge.

You stated you have a 3" MAF. So you would need a 3" to 2.5" (or whatever size your UICP is) reducer for each side (2 of them). I would recommend using T-Bolt clamps also or you might have a difficult time with the intercooler pipes blowing off.
