I am seriously considering purchasing an ECO 3 system.
They say they can enhance mileage by 10-12% or 1-2 mpg. Anybody beside Tschreck using one of these and what are your results?
Thanks in advance.
Oh btw the dealership just did a 2 degree advance for me (for free!) and my scan guage is showing that this has helped in addition to the extra power (if you can keep your foot out of it).
