How much boost should i get with the following mods:

3" RMM DP,
3" Catback with no muffler (straight pipe) only resonator,
BCC

I'm getting 18 psi in 3rd gear pulls and 20 psi in 5th gear pulls. Does this sound normal?

Sounds a little high to me. So you have totally stock hoses? NO boost controller at all? If you did that on a cold night (like we have been having in NY) then it could be possible though. A little higher than I personally would like to boost. Check all your vacuum hoses just to make sure.
