I wish I had an answer for you... I haven't even drove the car in 2 weeks, it just sits there while I slave away at work... so I haven't done anything with it yet.
But!! I hope to get some time to call (before Friday) Amercian Muscle about the Bama tune and also Steeda... so I have narrowed it down to 2. Whoever is the best salesman on the phone will probably earn my business. I like the Bama's free tunes for life... so if I add more accessories, I can just get a new tune for free. And I like the "known" reputation of Steeda... I'm sure they know the new 5.0 well.
I will hopefully have the tuner and the tune loaded up before this time next week. I will report back after its done!
Thank you all for the advice!!!
