Thanks Asur, a bunch of factors involved. Never was exactly clear on the term "vacuum", but guessing it's the suction force or negative pressure created by the downward movement of the pistons with each revolution? Would make sense though about the ECO light. If that's the case, the more I'm on the pedal, the lower the vacuum?...and turning my light 'off' ?
