The ECU on them is too complicated
The ECU gets its boost signal from a pressure sensor on the inlet, this is where you would have to put your resistor to trick the ECU. However, tricking the ECU will also reduce fueling which is mucho dangerous. Conventionally tricking an actuator wasnt as bad, as although increasing boost the fueling was the same, and not reduced.
On the Seat the ECU even reduces boost should it peak to high, so tricking it to go higher, would just cause it to reduce it again, but cause problems with fueling along the line.
Give Revo a call Jim, my mate with the seat looked at all this before he got his done, and the safest, best (And only I belive) was to have the Revo ECU and controller fitted.

If that's the case why don't you simply put a low resistor in one of the wire controlling the wastegate solenoid.
Pretty easy to do for any DIY person.
