If you do some searching on this forum you will find alot of info about programmers. Lots of people have the edge and gryphon. I personally went with the SCT X3. I would talk to mike from 5startuning.com He has great customer service. If you should run across a problem or a question you email him he emails right back with a solution. You call him he answers and will help you. I would get something with custom tunes. I have 91 performance which wakes the truck up alot, 91 tow which helps with some gas mileage and dont even feel like you are towing, and then 87 econonmy which is great for just crusing around. I would recommend this and have heard nothing but good about the SCT. I have heard pros and cons about the edge and gryphon (which is a edge but with custom tunes and not made by edge just looks like it)
Nice truck. Thats what I want my truck to look like. I have been trying to find a dark blue truck with pin strips to see what it looks like and I like it. I have also been contemplating on a tool box with whips on it but dont wana get rid of the tonneau cover cause it helps a little with gas mileage. I got 33's cause thats what I could fit at the time. 35's are next I cant wait.
