Did this last night, I opted to sacrifice the resistor pack side of the loom to leave the ECU side in tact so this is reversible if needed. I am a shit solderer, a mate told me more heat into the wires would help the solder penetrate better. That said I tested the wires before twisting and after soldering for continuity. The soldered section is also heat shrink wrapped under the tape. The whole thing is hidden under the fuse box now and cable tied to stay still.
Scaled injectors down to 48% and took a guess at latency (added .35 or so). Car started, and rev'd much more cleanly, no hunting. Still a bit rich though.
I also found feedback loop control in the PFC and turned that on, on was easy to tell as the warnings were all set to a specific symbol, knock, injector etc, but the boost control kit was set to a different symbol.
