I talked to Eric awhile back about tuning my brothers f-150, he said he did tune the 5.4. However my brother ended up selling his truck and never got the tuning so I cant be much more help for ya LOL.
Not off hand man, I do remember him saying something along the lines of not needing gauges/monitoring so all that was needed was something like an X3. I will look back into my emails and see if I can dig up the info..
I got custom tunes from 5 Star Performance for my F150. I was impressed with how they woke the truck up. PHP also custom tunes 5.4's but they use their own programmer which is basically an Edge Evo.
