you could always format/save them as a jpg and upload it as a picture?
I am going to be honest.. .I am new to Subbies but not new to turbos and tunes (still waiting on my WRX) coming from a tuned Volvo S60R.
Typically what I have seen with boost levels not holding pressure in higher RPMS could either be:
1. Turbo Control Valve?? Not sure what they are called on Subbies or how they work on these configs but usually with the newer turbos there is a valve that sends the correct amount of pressure to the turbo. Similar to a boost controller back in the day but that was to manually control boost.. this is a solenoid valve that is controlled by the ECM. If this car has one, maybe that is only good for stock boost levels and needs upgraded?
2. There could be a small leak in your intake system causing a loss of power at higher RPMS
3. Do these turbos have a control bypass valve (CBV) on the turbo... typically where someone would install a blow off valve? If there is a diaphragm in the CBV... that spring might only be rated for stock boost levels and over time wear out so much that it will not hold boost at high rpms?
Once again I am new to WRX/STIs so excuse my noobness but I am hear to learn
