My 94 has a boost gauge that only goes from 20hg vacuum to 10lbs boost. However i saw a boost gauge in the stock location that goes from 30 to 15. is this just a different year? can I swap? I max out my gauge on both ends and i would like to know what my motor is doing. any tips??
 
I don't believe there is a stock boost gauge that has any good accuracy. If you want to really know a valid number, you'll need to go after market.
 
Not sure what a 94/95 has but my 91 along with every other Sc my body style has the 30/15.

My 90,91, and 95 all had 30/15

Buy an aftermarket gauge

something aint right because your boost gauge on your 94 is like everyother one on any year sc.

every other one i have seen is diferenr than mine. My gauge only reads to 10lbs. every other one goes to 15 lbs does anyone know why this is.
 
how about a picture

maybe the previous owner adapted a more accurate guage into the cluster.
 
well i wish I had some idea what my motor is doing. i idle at 20 hg so i dont know how low i am going under decel and at 3/4 throttle i am maxing out my gauge and it sucks. I want a normal one. I feel left out

my bad!! the previous owner put in a stupid brushed stainless gauge bezel from a lx so it covers the bottom of the gauge. I am a dumb a$$ i guess. if you look at it from the top you can see the numbers at the bottom. I might take that thing out and either ditch it or trim it so I can see. thanks for wasting your time to help me. I will try to know what i am talkin bout before i post next time
