I just bought the PFC and my friend with an fd told me that because I'm running full exhaust I will need to bore out my waste gate on my stock twins. I want to know if this is correct and if so does anyone knows how much I would have to bore out? Thanks in advance.

 

Yes, most of the time you will overboost with a full exhaust. As for how much, as much as you can.

Ok so there is know set amount. And as far as the PFC goes is it drivable with the tune that comes on the PFC

 

yes, of course, but just take it easy...
