The map reads 90 with key on and engine off. I just pulley'd down yesterday so haven't hooked it up since the initial run. The HP is definitely off, pulley'd down from 87mm to 81mm and now getting 675 at f/t, I'll probably pull it as it's a useless figure. Was curious about the output.

90kpa (13psi) is your standard atmospheric pressure then. The 14.5 is for sea level ish.

So if your map is reading 18psi then you are actually getting 5psi of boost.
