I have a edge evolution on my truck an a buddy of mine has a 97 F-250 an he has a bully dog chip he said he don't like it all that well so i told him i would trade him my programmer for his chip then i would just sell the chip to get one for my truck, anyways i went over to his house so he could try it an a friend of his pulls up in his 97 F-350 an he's got a superchip. He wanted to trade so took mine out an put his in my truck on hi performance mod. An it made my truck fell like it was on stock again . He pulled back up "an was like man what ya think" I told him that it sucked a**. I really want a good chip for my truck what would be the best one for me I don't pull that much an when i do it is a 16' bumper hitch trailer. Any info i would really appricate it.
