Question for gen 3 10 owners with a PCV

[Kawawog]

Hey peeps, just wanted to know if any of you's gen 3 guys are running a PCV and whether or not you had to buy the SFM(secondary fuel module) to get it all tuned right with the mods you have?
Atm Im running a k&n air filter and yoshi r55 slipon, but plan on fitting a link pipe(when i find one) to do away with the cat.. Will i need the SFM together with the PCV to get this thing tuned right?
I eventually wana go a full akrapovic system but atm funds dont allow it
Any help would be very apprieciated
