3.7L Tuner?
#2
If I thought one was worthy enough for my 4.0 liter mustang, one is certainly worth it for a capable engine such as the 3.7. I used to work at a local ford dealership (worst in west Texas my i add) and had the opportunity to drive many vehicles including all f150's. I loved swinging for that 7000 rpm redline when I test drove them and they still pull like a freight train. In the tiny single cab, short bed pickups they run like a mad ape on fire.

My guess is that you would have been better off spending your "tuner money" on a 5.0.
