If you get consult guages etc when communicating with the ECU then it should be 'talking' so then you can make changes
If it was running limp modde then where would be no comms. You should be getting oragne/green flickering during 'tuner mode' operations

I'll get Pete to get back to you on those solenoids since he does a lot of wiring for SR20s and knows what everything does
Have you turned off your O2 feedback flag also whilst tuning? Otherwise if the ECU is in closed loop will keep trying to get back to 14.7:1 afrs

You don't need the boost sensor input or WG solenoid. It should run fine without them.

O2 feedback is marked as 'Feedback Switch' for S14 with one of the flags 'O2 sensor'
Just untick that.
Other way is to selectively turn off O2 sensor in the fuel map by hitting 'O' against flagged cells when you highlight them
