Also, I love how peppy the car is right after a fill up. My GTI was the same way. The computer must switch to a "gas saver" map when the fuel is low, because every time I fill up an empty tank, it's like I gain 20 ft lbs of torque, lol.
Huh, I have not noticed this - I'll have to pay attention, do a couple hard rips right before filling. I've never had occasion to notice as when the fuel is that low *I* switch to a "gas saver" map LOL.
