I have a 2012 5.0. I added an air intake but it seems that the stock tune and exhaust is slowing the system down. I know the factory tune in weak and I'm looking for a tuner with both towing and performance preloaded tunes as well as one that can restore my factory setting if I ever need to. I also need to change tire size data for the speedo. I prefer to know what you are using or have used as well as what to stay away from. Thanks
