i'd like to get into tuning my own trucks, as i'm planning some pretty big mods, as well as gear and tire size changes. i just cant see spending the money for a reprogram, and then not have it be 'right'. if i do it myself, i can just redo it if it isnt right. what are you guys using as far as hardware and software? i'm currently in the market for a laptop, so i'll be able to do in vehicle tuning. lets hear what you guys are using.
