:banana:Now mind you I am a rookie at downloading programs but it seems I was sent a new power flash through evol perfom. No instructions- called Fred and he stated it says load custom tune -not on box anywhere- two options load pretune or custom- not on sctflash that I can find- can I reload the stock program and unload it back to the power flash and then add the custom tune- induction system only no pulley- wish I had the number two version- hate to be one of the first to have a new item that was why I waited a year to pick the air induction system- believe the custom tune is programmed if that is the one I need- but when you plug in it does not let you know what you have -will one program overide the next or do you have to reload stock to be sure you are correct? I know I have a program in that is not stock as the gt 500 is crazy powerful with the super charger screaming like hey man what going on- any download tips or thooughts on the x3 a[[reciated
