Awesome! I believe perrin (?) tested the EFR7064 to be later spooling then stock and the even smaller one (6458?) spooled faster, but now this 7163 spools as fast as stock AND gives wayyyy more flow/hp!

What made this happen all of a sudden as a 7163 looks like its the same-ish dimension as a 7064 and parts are as light-weight as possible already with the EFR line? More aggressive trim?

320 hp at 4000 rpm! Wow!
