I found that both the air-filters were extremely dirty and one was nearly clogged with small leaves and bugs! This was only after 3 months of driving! So I changed the filters. I also installed a vacuum gauge, this was i think the most helpful. I also ran some top cylinder lubricant in the tank along with ethanol free gas. I managed to beat EPA highway today on drive to work. I turned off engine at every redlight and during highway driving i pulsed to 30km/h above target speed and coasted in neutral until target speed. I just rev matched the gears to neutral->drive was smooth. Pulsing was done at highest gear possible at around 1800 RPM with only ~5in-hg vacuum. Quite happy with 12.2L/100km highway. It's a vast improvement and if I keep it up then I will save $30 of gas a week. enough gas and money for the weekend auto-cross!
