I know Dinan, AA, OE Tuning, BMW PPK are all ECU "tune". But I want something that can be reversed by myself. All "tune" that you referred to can only be tuned back to stock by the company if it's reversible. JB4 and Procede are piggyback "tune". But both can be installed and uninstalled by user. And that's a big plus for a lot of people. By the way, I did not invent the word "tune" when referring JB4 and Procede. That's how and refer Procede and JB4 as "tune".
