Well I finally got off my ass and hooked up the Auto Meter boost gauge thats been chillin in glove box for 2 months now. Works good. My ? is what is the normal boost level for the 03 230? I'm reading between 7 and 8 psi in first gear when I put the pedal to the metal! LMAO! Any of you guys got any real world PSI readings (not what the manual or google says it should be) that you care to share? I just got it hooked up last night and am basing my PSI on what I saw on my way to work. I'm gonna find an empty street and see if I can get more accurate readings. Thanks.
