Buy the tuner from Lund, VMP, JPC, Rousch, Steeda, etc. and it'll come loaded with 3 tunes from them that'll probably set you up perfectly fine. The tunes come essentially free with the price of the tuner...except for VMP, which dings you with a little higher price and shipping compared to the others. I used them because I wanted a totally solid auto tune and they are known for good work. We are talking ~$50 difference so, NBD.
Don't use SCT strategy tunes from SCT themselves. These are risky and don't have the development time behind them the players above do.
