RE: Holiday Boost Gauge Install!
so with seeing my boost at a max of 17 and an average of 14-15 do u think i have leark.
I have some weird japanese boost gauge (name brand: swoosh) and the instructions say i need to calibrate it, but i just don't know how to do that.

RE: Holiday Boost Gauge Install!
That's why you buy a good name brand gauge. What kind of calibrated pressure measuring equipment do they expect you to calibrate it with, a bike pump and tire pressure gage, WTF? Does it read '0' at least when the engine is off and the key is on? I dunno what GIAC chips put down for boost, but mine holds at 16 psig and I'm pretty sure i have no leaks.
OK - is 12 in Hg at start up under higher ~1200 rpm, or is after the car warms up a bit and idles down to ~800 rpm. At 800 rpm, the vac should be ~ 20 in Hg.
Good luck with finding your leak, I'm about to be posting up some pics of the car with the coilovers.

RE: Holiday Boost Gauge Install!
well a search revealed this-
METERS AND SENSORS ARE ELECTRICAL - MEANING SENSOR IS REMOTE MOUNTED. SELF DIAGNOSTIC FUNCTION TO ENSURE SENSORS AND METERS ARE FUNCTIONING PROPERLY.
so its an electrical boost gauge, which means it should calibrate itself. i think you got a vac leak

i've never heard of someone having to calbrate their gauge, usually the company does that. and your slightly low numbers make me think vac leak as well. my k04 went from holding 15 psi and spiking 18 to holding 22-23psi after i fixed my vac leak. does your boost spike higher in the gear, or spike right away then fall off later in higher rpm?
