So 550RWHP is fun but ready for the next level, I've already upgraded fuel pump to handle more, basically as far as I am aware I need to upgrade 2x pulleys and injectors.

Are these the right pulleys to up boost a bit??

Already running S1.SE fuel system etc.. + this air to air kit and blower upgrdeded with Si trim.

I've got the Tbat pulley on the front, was there something else needed on supercharger side?

Now I'm seeing something about head lift somewhere? do we do ARP headstuds to stop it or?

Cheers guys!
