1. tune is the problem, they should sort that out. easy fix.
2. although the frozen boost can help, It really isn't the big problem, The after cooler is way to small to cool these engines. MAF postion aswell.
3. I highly doubt the frozen boost will help the motor put out more emissions, it might put out a little more, but it should still be CARB approved.
once the car is epa cert. put the intercooler on and call her a day
