Re: PI swap?
Yah the PI swap has basically been done already from the factory. As said you could P&P the heads to gain some hp.
Supposedly the gains from the Trickflow setup are real good but for the money I'd rather pick up a centri style charger and run low boost. Then rebuild the lower/top end after some catastrophic failure using stock internals lol.
