Purchased an In Tune, looking to know what delivers the most power, better shifting, i.e., IF IT WAS YOUR TRUCK< HOW WOULD YOU TUNE IT?

Vehicle: 2007 Dadge Ram 1500 5.7
Mods: DIY 4" CAI, Magna Flow Catback Exhaust

Should I load 91 tune? shift points, shift pressure....? Never owned a programmer ...
