Edge Evolution
I got a free edge evolution programmer from my buddy today. He sold his truck and bought a 250. First question is can I use it since it was on his truck and is it worth it with my truck having 216k miles

I picked up an Evo for my '98. Wasn't free, but because it's an older model, and cannot do custom tunes, it was around $200, as "new old stock." This was instrumental for getting rid of those dreaded "lean" codes (no vacuum leak present). This also helped me resolve a gauge cluster problem, where the tach was reading 700 RPM over actual. Did it really change performance or add MPG? No. Worth it? Yes.
