I will also add, just keep in mind, your 9.45" lower + stock sized upper is an apron. 18% overdrive.... whereas a 2.3" upper + 9.17" lower is an approx. 24% overdrive... which is could be worth approximately. 1 - 1.5psi on your build.

Your power numbers seem inline with the mods listed to me. Sounds like a healthy build!
My lower is a 9.65 should be a 20% overdrive I think right? I was told to avoid the smaller upper for belt slip purposes.
