im curious to see if anyone is running a bigger or aftermarket throttle body while running the JRSC and how much of a difference it makes. and which throttle body do you reccommend

please let me know if there was a difference (worth the money wise)

 

When I had the JRSC. My stock throttle body, and manifold were bored, and port mathced. It makes a slight difference... Every little bit helps thought.
