Have you considered a 6 liter tune? Also could you show how you attatched the air filters?

 

It's been along while since I posted here. Been busy with work, and over the summer my Ford started giving me problems. Started with rough running engine that lead quiet a bit of blow by. Ended up putting the factory air box back on. And a new PVC valve on and it runs great! Ended up buying a brand new truck to get me to work though. So I've decided to spend some time on my f150. Plan is to rebuild the engine with custom forged pistons and run a turbocharger at about 10-15 psi sized smaller for low rpm boost. Gotta go back to single exhaust lol. Anyway gonna try to be a better member and help out more. I'm a ase certified GM tech so I may not be much help! Heres a couple pics of my work.
