Doesn't make a lot of difference as long as you get the restrictor pill size right on the 2-port configuration.
A newage WRX will need a smaller restrictor pill to get more then 1bar boost from it.
Regardless of what the BCS duty cycle is set to all the intelligence within the ECU still won't get it boosting, it all comes down to a small piece of brass with a 0.9 - 1.2mm hole in it.
But then your mapper would know that, unless of course he's trying to flog you a 3-port, instead of a £0.99p restrictor, where there would be no profit margin.
