Hi, me and my father have a 2003 GTI 1.8T 5 Speed and we are looking to get better gas mileage out of it. I know dual Exhausts would be a good way to improve efficiency but what other modifications would help up the mileage?

I'm a proud owner of a 06 MKV 2.0T and have come across an issue... I just noticed today that my mpg screen in the dash is acting weird while I drive. It went up to like 106 mpg then down to like 6.8 mpg. I've never had this problem ever since I Baught the car up until now... Someone tell me...

Is anybody [other than me] interested in this thread? City: 21-24mpg Highway: 29-31mpg I'm stock; other than a spectre p5 intake and some old lowering springs. What are you guys [especially those of you who are chipped] getting in the city and/or on the freeway? It would help a lot if you...
