Hi, I am new to the club as well as ownership of 06 E55. Was thinking of getting a ECU tune. For those of you that have the ECU done, how much did it affect your fuel consumption assuming same driving conditions

Thanks.

I have LET Stage 1. My mileage actually went up a little in normal driving by 1 mpg. Used to get 19.5 at 80mph highway, now get 21.0

Note: my average MPG is 13. But i get more per mile than before so its worth it.

My fuel consumption really hasn't changed in "normal" driving. Of course, I floor it a heckuva lot more now! LOL!

Should be better because most tunes lean our cars out (rich from factory).

My fuel economy went to *****...that's prolly cause all the new found power gets me giddy everytime I floor it...


Torque...it's a helluva drug...

I would say if you're worried about how much gas you use, DON'T GET A TUNE Tune it, Punch it, Race it, Any Questions?:nix:
Tune it

A good tune will increase the efficiency of that big air pump we call a motor.

More efficient: better mileage

IF you can stay out of the throttle, that is.

My gas mileage improved a little with my Renntech tune and pulley.
