2007 silver MS3
I just installed my boost gauge today.

What are the numbers other people are seeing?
I think I had 5-6 psi in 1st and 2nd.
10 psi in 3rd.
15 psi in 4th and 5th.

Also this is my first turbo car should the boost hit the limit then fall down a little sometimes?
 
I guess this is normal, I know the ms3 limits boost, I'm just wondering if these numbers are right.
 
seems pretty low to me. what i see

1st.....8 psi.
2nd....12 psi.
3rd and up will spike to 20 and hold 15-17 psi until but falls to 6 psi at redline

i only have the MS CAI and greddy bov on the car now.

What Greddy BOV? Using the Greddy RS? I was looking into getting that on my car I really want to see what is sounds like on the MS3. Or atleast get some word from someone who is running one on the car.
 
i highly doubt your factory ms3 is boosting 20psi unless you are getting a spike or your boost gauge is not reading correctly.
