I am not sure why you're so negative about something I would like to enjoy. If you don't like what you see, then just don't bother looking at it. There are many people, including me, who are interested in this stuff, and I just wanted to share the news with them. It's obvious you aren't one of them.
it is quite obvious that these other members have good knowledge about ECU flash, especially used on non turbo vehicles. They are entitled to their opinions even if it is negative. I mean i have a 328i and thankful that you could share this information but i too have doubts we would see much gains. You say there is a return period, so that is cool that you want to try it out regardless, just let us know how it goes.
