Hello All;
I've been on the post w/ my '03 step-side 2 doors and 3 pedals F150.
I finally traded it for a 2 pedal truck! (only because you can't get a manual unless you go across the sea). Remained 2-door true w/ the new Tremor.

I liked the idea of the last of the real-steel, and that the 2014 Tremor was a 1 year only model. I waited on deals, and finally got it late last year. I've only made a few small cosmetic changes. Set up the way I want.
No performance changes at all...Yet!!
That's my question. If you have a fresh 3.5 eco, What are the 3-5 best performance upgrades.
Also any other Tremor owner tips out there?

Thanks, Todd
