Ok i am by no means very good with engine's, I just know i'm not getting everything out of my truck that I could. I've got a 2005 fx4 with a 2.5 AL leveling kit and an edge programmer along with true dual exhaust. I have played around with the edge on custom tunes but have not found somthing that I think really makes my truck get up and go. Please help on some tunes you would think would work, I am running the higher ocrtane gas also. Any other thinks that would help with ponies under the hood would help.

Thank's alot guys
