[t-bone]

Okay I'll just admit it right off the bat, I don't have very much experience with Ford engines, so you'll all have to bear with me a little. My first question was whether any of you guys or gals have used one of those little gizmos that you plug into your data port and can fine tune the engines performance? I know they work on the gm 3800, but I wasn't sure about a 11 year old N/A 3.8 liter Ford engines. (If someone has already asked this question and it's been answered in another thread, just point me in the right direction.) Thanks.
