I've got a 04 stage 2 redline. My interceptor gauge is reading ,under hard driving conditions, all the way to 15psi but my mechanical autometer boost gauge never goes past 9psi. Whats the deal? Both read exactly the same vacuum and boost up to 9 psi, then the interceptor advances and the autometer stays at 9. Any advice will help, thanks.
if your mechanical gauge isnt working 100% maybe a hose kink? or leak? loos ground (on the gauge) on WOT(cause the whole car moves).. check those and report back
