Re: Stage 3 Snort FFI turbo on 4.1 XF?
XF's dont like to have boost running through the standard airbox/meter, but it can be done with a good tune, and adjusting the air meter/air box flap. Legal wise it is illegal to have, but your not going to get busted by the cops are you? You can get an engineers report anyway and make it legal. Not sure for installation costs, have a crack yourself and its free ;-) It all depends what boost/power you want running through your engine, a borg warner auto has no chance of standing any power upgrades, you would need a C4 auto. http://www.snortperformance.com
