For example, if the on-board ECU used injector pulse length to calculate fuel use, but you had larger injectors, then when cruising the injector pulse would be shorter because the injector is larger, but you are probably using the same or more gas. I just have a very hard time believing that a TT sports car is rivaling hybrid gas mileage on the freeway.
I believe it does it exactly that way. I've watched my fuel closely since adding my turbos and it definitely hasn't increased even though the on board computer says different. The larger injectors trick it. I drive mostly highways and am pretty conservative and I normally get 300 miles to the tank now. Here's an example of my gas mileage according to the car. I keep telling people I have a hybrid lol. The last picture is what I was getting before the turbos.
