I've read several forums on programmers and tuners and there seems to be mixed opinions on what is the best. I plan to run an AF1 3" on my '03 4.6L. I'm leaning towards edge because of functionality and availability as opposed to Xcal custom tunes. Any thoughts?

 

You have to decide for yourself. All I wanted was to firm up my shift points and have the availability to change tires sizes. I ended up buying a Superchips Micro for $209.00 off ebay [new in the box] and if I had paid the full price of $400.00 I would have been disappointed but for the price I paid I got what I was looking for and am satisfied. If you are looking for a kick in the seat a canned tuner is not going to do it and you will need to go custom.
