because i have it set at 5psi.. i had it tuned at MRD and had them leave it on 5psi. I have an apexi boost gauge, as does my 2 other friends with a 89 prelude and a 99 saab viggen. we where wondering why they went all the way to the 20 mark also so we asked around. maybe its just the kind of boost gauge we have but all three of us have the same one and they all read 20 when we hit them hard. the prelude it running 12psi, the viggen is running 15 psi, and im running 5psi. sorry if i was wrong but thats the conclusion that we came to. i doubt that all three of our boost gauges are hooked up wrong seeing that mine was hooked up by MRD and the viggens is stock and the prelude hooked his up himself.
