I've been running 9.5-10 PSI for around four years now. Mods include:
Perrin FMIC
GHL TBE
SS AFC v.2
Protege Garage IM (port and polished)
Greddy EBC (meticulously tuned to get proper boost)
I actually don't boost a lot while driving, but when I do it pulls strong to redline and hasn't given...
Rear caliper, rear rotors, and rear pads will be replaced tomorrow morning. Thanks to justagirl@mazmart for the caliper and Tri-Point for the rotors and pads :)
