Im also from Toronto, my stage 3 aero gets about 9-10 L/100km on the highway on cruise and 11-12L/100km city but i always drive fairly aggressively, the best things i can think of, is check for boost leaks, fuel filter, bad plugs and a failing 02 sensor. I also had the temp sensor slowly fade causing the car to think it was warming up constantly and that wastes A LOT of gas.

When was the last time you had a CEL and what was it?
