So i have all intercooler piping, twice as big sidemount, type-s bov, air filter. Nothing on my exhaust is touched.
Last night i just installed my cobalt blue boost guage, and in all gears above 2nd my boost spikes up to 20 and then falls down to 16-17 depending on gear and then drops off after 5500 rpm or so.
I have no boost controller, i didnt remove the BCS restrictor, so i should be at 15 psi. But w/ my mods i know this isnt possible
MY QUESTION IS, is it safe to be spiking to 19-20, then going down to 16-17 psi with the stock fuel pump rewired. I use 93 octane no matter what.

BTW, getting an Extreme Motorsports XBC, and bypassing your BCS solenoid will fix this problem.
