18s will have direct and port fuel injection, just like the yote. So fueling wont be an issue. $1500 in engine option difference + $600 for a tuner, drop in filter, and catch can is a HELL of alot less than a $7000 blower setup. Plus labor depending on who you are...
The 17 3.5 already have it dual injection.
I was referring to the person who said in order to get on the level of a 600 rwhp coyote F-150, it would need upgraded turbos. I'm sure parts and labor for such an upgrade isn't cheap. Seems like a lot of work to keep up a with single mod 2nd gen Coyote F-150.
