I wouldn't go much over 16psi. After that, the T-2small just starts blowing hot air. Also, before you up the boost, make a pull and log airflow. Then after turning up the boost, log airflow again and make sure that youa re getting a corresponding airflow increase. If you aren't, I would turn the boost back down.
Remember,
Airflow = power
Pressure (psi) = heat
