I'm running stage 1 aggressive + FMIC, there is no difference in fuel mileage from stock BMW, If I drive easy!
If I am enjoying the added boost from COBB, well my mileage is less, no shit!!
Understand, air and fuel burn at a certain ratio, so when you pump more air into an engine, you will burn more fuel. Well when you increase the boost you are adding more air to the engine that requires more fuel.
This has been simplified for those that do not understand stiochiometrics, for those that do, please don't reply.
