What is your commute ?
How do you drive ?
Honestly, I can't see much FE improvement coming from ecomodding the car.
It is already very much refined to be performance vehicle with a very big engine and such.
I tend to drive spiritedly once in a while, coming from motorbikes.
Thing is I have much more fun going flat out with a much smaller engined vehicle than I do allowing me to break the law once in a while with my regular car, not to mention the safety issues. And it's not even sporty !
So I seem to recall you're telling us that you use a M3 as a daily driver and that you don't break the law with it and that you drive hard on the track ?
Yeah, right !
Each to their own but an econo box on the side of the M3 is going to pay for itself in no time ...
Try P&G one of these days, it's much funnier than you think.
