I wanted to see what sort of boost levels I was getting with the SQR Stage III ecu. Boost spiked at 18psi and levelled out to around 16psi up to around 6k rpm and dropped off to around 14psi at rev limit.
It seems like the T7 is very active in controlling boost since it was variable throughout the rpm range and different load levels. Boost would increase and decrease slightly throughout the rpm range. I'm not sure if this is how it works or if it is sensing ionization and cutting it back slightly.
The VDO gauge I used also vibrated a little when the boost came on hard at spoolup.
