You can do remap of ECU for DI. The ECU map can be changed only by that tuner that did the previous remap. The ECU can be set back to the stock baseline set points only by the tuner of current remap and then ECU can be given to an other tuner for a subsequent remap. The current tuner can perform subsequent changes to his previous remap of that ECU.
There will be a company in WA that do remap (live or postal). I used ECPT (Tuggerah, NSW) Harley Anderson (Technical contact) who has a good reputation and does postal remaps and live tunes. Can send him your ECU for postal remap and ECPT posts it back, maybe 2 wks turnaround time. A remap can turn EGR off to prevent limp and with stock turbo/IP/injectors, his tune provides for max B 20-22psi / AFR 19 - 22:1(depends what your needs are_towing etc).

Question: Your max boost control is Dawes, so do you use needle or use VNT vac solenoid to control spool?
