Hello-
I'm a 2001 TDI Jetta owner looking to squeek a bit more efficiency for my 22 mile round trip commute. I run B20 and just ordered a ScanGuage II from JCWhitney for
$159.99 with free shipping and a $50 JCWitney giftcertificate.
I need to read up on many things but I think I'm going to start with tire pressure, driving habits, and possibly blocking off some of my air intakes. This site seems like an excellent resource.
