65 MM Throttle body for Roush Stage II?

Looking for maybe a little grunt for the Raptor which has already had JDM tune installed. Just wondering if it's worth the $$ and also, does JDM need to re-do the tune for it.

I put it on when I went to my Roush supercharger, so I have never driven without it. However the installer had another Roush without it at the shop at the time and said the difference was noticeable. I have a JDM tune for it.

Thanks Dane!

Throttle body and intake restrictions are a big deal with PD superchargers. Gains (or if you want to view it from the lens of restrictive losses) can be significant.
