Thanks for the recommendation(s), Protune, Alpina Flash and an oil cooler are the next mods I have planned but I wanted to also ask; why is it so much variation we have in everyone saying they are able to run this type of E and that type of E without having any issues or minimal issues.

Some are running E without no tune whatsoever and the most they are getting is either running too rich or too lean but nothing seriously damaging any internals or causing detonation of any kind?

Is there a specific safe spot when running our cars without a tune while using E?

Yes, COBB AP. The original 93 pump tune was $200 I think if I remember right, that's with the forum discount they offered.

Any additional tunes after that are $99. I have not dyno'd, Im an xDrive and I do not know of any all wheel dynos here in Central FL. Im sure there is one, I just haven't looked too hard.

Do you have any logs you could share in this thread?: http://www.e90post.com/forums/showth...1183928&page=4

A lot of people are having issues running E50. Your logs and maybe some input on driving habits would be helpful. Some people have success for a day then the misfires creep up.
