Ed at Balanced Performance tuned my SOHC supercharged setup, and my turbo setup with a t3/t4 at 15psi about 3 years ago. Its my DD and I beat the shit out of it and not a single problem yet. Then JJSPEC street tuned my EF Hatch t3 setup at 8 psi, and that motor had 160,xxx miles on it. Again no problems.
