I'm about to drop a nooby question on ya'll...maybe it'lll enlighten some others as well though.
It was brought to my attention that the Cobb AP boost gauge (probably) only reads in PSI. What this means is that the vacuum you're seeing is in PSI, and not in/HG. Until my big turbo upgrade I always assumed that our cars just had weak vacuum. Since I'm running a GTX, I'm using a Tial Q and this is where the question came from. If the Cobb AP is indeed reading on in PSI this means one has to convert PSI to in/HG in order to find their true vacuum. With that number one would choose the correct spring/setting for their BOV... Now, since our cars are MAP/Speed Density tuned, it's not a HUGE deal, but I'd still like to have this confirmed/debunked.
Maybe one of you with extensive knowledge can chime in? @ian@cobb [MENTION=688]Sourskittle[/MENTION] [MENTION=3178]maperformance[/MENTION] [MENTION=1098]drag4life723[/MENTION] [MENTION=930]dyn085[/MENTION] or anyone else that knows.
