there isn't a straight replacement ECU for a Wagon that will give more power. Unlike the saloon where a Z4 will give 20ps more then the earlier ECU.
You have a Td04 Turbo so you are limited to WRX Wagon ECU's which all run the same/similar maps.

You can fit an uprated chip into your ECU though that will set it to run 14.5psi (standard is 10.5psi, dropping to 6.8psi).

As Scott T said check out PolarPerformance (which he runs) but Jolly Green Monster - ECU Mapping does live mapping of them and Bob Rawle does it.
