Im about to be, just need to buy it. IMHO it the best tuning software out yet. It has a scanner AND tuning software. LS1Edit, you have to buy and then buy a scanner such as EFI Live.... Also, HP Tuners is NOT locked to the VIN number, only the year. So you can tune any car for that year, not just yours. you can also incorperate a wideband onto the scanner software...
