For what it's worth, I sweet-spotted my T2 when I first got it, and found it to have a long bell curve, maxing at about 310 fps at 310 psi with the IVG backed all the way out. I ran it on the front end of the bell curve - 205 psi shooting 275 fps - for my first couple cases, and it loved shooting at that pressure... right up until the valve spring started to break in and it had trouble keeping the valve closed. It was plenty efficient at that setting, but not noticeably quieter. I'm now running at 330 psi to shoot 275 fps (on the back end of the bell curve) and having no issues.
