my 2012 dynoed at 148whp 139wtq no mods with the powershift so Ford underrated it greatly. I believe another one dynoed at 148whp and 143wtq with a manual.
I think turbo is a smarter choice any day of the week in my opinion. While the Roush kit is cool and all thats just another drag on the motor at the same time as being an adder.
The ST will hopefully show us power and great gasmileage is possible.
