If you're going to want some power and a fast truck I would steer towards a MADS product. The smarty will put down some big power but if you are afraid of messing things up there is the smarty junior which from what I hear is a great programmer. Also bully dog is a great programmer for power actually have had it on my truck for 2 years about and it ran great. Those in my opinion are the best two brands for programmers you just have to do the right upgrades if you want the full potential of them. You can always just run them on lower settings if you are afraid of hurting your truck. Also once the bug bites you you will want to be doing more and more so make the right choice the first time. Just my .02 cents.
