04 2500, has banks six gun with the old school pda set up. been looking at getting a smarty. just wondering if anyone has experience or knows if i can turn my 6 gun to stock, flash the smarty into my computer then plug the six gun back in so i still have my system monitors ( boost,egt etc.) been thinking about the smarty ssr also so i can play with building my own tunes. just not sure if it worth the hassle in a work truck.
