Hello, I am just starting to tinker with some tuning and learn. I have a 2006 E320 CDI that I upgraded the turbo/injectors and did a remote tune. Doing the remote tune got me interested and I installed the trial version of winOLS to look at the stock tune and upgraded tune to see if I could figure out what was changed. I figured I would join this forum to learn a little bit more and possibly move on to tinkering with some of my other cars.
