3" ATR DP???

[turbov6joe]

Any opinions, be they good or bad, on the 3" ATR DP with intergral wastegate??? Currently I have the ATR 2.5" DP that uses the OE exhaust eblow. I made 426 HP with it and am wondering when the airflow will exceede this units' ability to pass the gasses I can get the ATR unit for wholesale, that's why I'm heading that direction.
