Re: tuning a turbo?
I have worked with a lot of guys who don't have dynos anywhere near them, for hundreds of miles, so its not an option.
What I do is sell them an X2 and LC-1 wideband, costs around $700 including the tuning. They gather a/f and OBD2 data on the street according to my instructions, email it back to me, and I email them new tunes. Just like a dynotune but over the internet, a remote tune.
