Quick and easy - 2010 fJCW, Alta CAI, and resonator delete. The car hasn't quite had the ***** it did back last fall when I picked it up, and I've not seen more than 15-16psi on my boost gauge since I put it in a month or two ago (Autometer mechanical gauge reading off a NM boost tap).

From what I'm seeing, a fJCW should make more like 19-21psi in stock form, right?

 

That is about right. Maybe even a bit high.

If you are tuned you may see 19 to 22 psi or more.

I have a 09 JCW with a RMW tune. I see 20psi on a regular basis. I have the VEI hi res digital boost/vacuum gauge that get its reading from the BSH OCC boost tap.
