Just got my wife a 04 2500. thinking of a programmer for it some time soon. Interested in some pros and cons, and expirences from some of ya'll.
I'm leaning toward the Edge A2, lots of extra goodies with that one.

 

Programmer- hand held device plugged into the obd port. Uploads software to the truck's ECM.

Module- box that intercepts computer signals, hooked up all the time.

Programmers....choose a Smarty or a Triple Dog.

Modules....Juice/Attitude, Quadzilla XZT or standard, Dr. Performance....


Since you inquired about an A2, you must have the Edge Juice to make the A2 work. I wouldn't know anymore since i haven't been keeping up with it, but i used to have an A2. Edge bought it back because it had issues they couldn't fix...and those issues continued on for months. Edge bought mine back 5-6 months ago i think. When it worked, it was awesome...but half the time it messed up.

I've decided i'd rather have the normal Juice/Attitude and a stand alone GPS....plus its about the same price. I had to pay like $1100-1200 for my A2.
