On that truck it really depends on what you want your chip to do. Are you just looking for a simple power upgrade or do you want to get as much power as possible. Do you want user interaction, gauges and lots of safety features. Both are available to you would stick with edge and superchip. Edge gives you all the bells and whistles for around $719 where superchip is more basic but still very good for around $399
