You can only safely assume that if they have your car in their possession and are dyno tuning the ECU.
The easy thing to do is get the JWT ECU and then the NISMO Adj Fuel Pressure Regulator. The JWT ecu is going to be real close to what you want. You just need to confirm it on the dyno and then fine tune it with the Adj, FPR. That is what I have done and it works great. I gained 10whp NA.
