American Trucks has put together a guide about the Ecoboost series of engines in the Ford F-150. How they work, different displacements, capabilities, upgrades and common problems:

Weird, I just tried it again and it worked for me. I'll contact them to see if something is up on their end.

 

Okay, fixed. They had both .htm and .html at the end of links in the email they sent. I pasted the htm link which isn't working anymore (cached in my browser). Link has been updated, should work now.
