Yes, undoubtedly help producing more power up top and improving thottle response very clearly all over the entire rpm range. It takes a lot of time and dyno work to extract the utmost performance out of it. Switching back to a zero map shows the dramatic difference in behaviour, specially if you have mods like increased compression or head work.
There is a PCV IM now though. It's a matter of budget. You have all the hardware already so better try to tune your IM first.
