    Stock Psi for Evo 9

    So i just installed a defi bf boost gauge for my car and am pretty sure i did it correctly. I was just wondering what the stock psi for an evo 9. My gauge is showing a peak value of about 18 psi and i thought it was only supposed to be less than 15. To help, I only have a catback exhaust, drop in filter and NO mbc. any input would help thanks

    Peak of 18 is fine. You should see it taper towards redline though.

    Spiking to, perhaps. But it tapers far from that...stock.
