This is my first diesel i know a little bit about diesels.... I know on the "dodge rams"when you add hp you usually gain mpg. my car is a 1985 jetta td. it's a daily driver/commuter just looking for ideas on how to increase power and mileage. If you have any ideas please let me know.

P.S.-thanks in advance
A bigger and more free flowing exhaust and intake will allow you to turn the fuel up with out a rise in Exhaust Gas Temps (which are bad).
