I'm new to tuning a vehicle as I have always owned fox bodys.I want to know would be better tuning my stock 2011 5.0 with a hand held tuner or taking it to a performance shop and allowing them to tune it for me with a dyno.I have looked into both but haven't decided what is better.I assume if a shop does it i'll have to take it back every time I want to bolt on or change the tune for whatever reason.Any professional info would be greatly apperciated.
