Hi gays. I am using unleaded 95 octanes on my 300E and 190 E, 2.6, year 1988, because it is more clean and has better quality control.
Our outside temperature is 80 Farengheit degrees around the year and relative humidity is 60% or more.

Then, I have to calibrated for a new air- gas ratio?

The % readed between point 2 and 3 in the X11 diagnostic plug has to be the same 50%.?

How to get more power and efficiency?


Thank.

Mario Farias
