Any recommended tuners in Charlotte area?

Sorry I am such a noob but I work in a District Attorney Office and am not good with doing mechanical work as well as do not have a lot of time. Do you have to take dash out to put a dsp5 switch in and is it hard to put in and get hooked up right? Programming through the port is not much of a problem. Thanks in advance for all your help.

I understand EFI Live is the Bible as far as best, but do I really need to buy one or I have seen them on here where they will send you one and the switch and you program your truck and send it back? Whats the best way??

with the spade tuner, I like dual exhaust so do you have a dual exhaust package that would work well with the spade? Package deal?????
