Hello Scott,

Thank you very much for commenting, and saving me a fortune on the v2 flash scan. I am building this vehicle for my personal use, and I will not be using roadrunner for commercial usage, just for my vehicle and my self. So thank you very much for making it clear for me. I will be using EFI Live software, becouse it seems to be more friendly for user. I will still have to learn it, becouse i never used it, but as i know TunerCat iss much more complex to use, is that true by your opinion, regarding thet you are using TunerCat, and you are used to it?

Well and plus to all, EFI Live license are cheapper than same license for TunerCat...
