I would look around some more for the go-fast VW guys.They have tuned these things to every possible situation.They can tell you how to set up for highway cruising,high speed running,low speed-high torque,good fuel mileage,anything you need to know.Lots of know-how out there.I have a much harder time trying to find info on stock versions.I am sure it is out there,I just have not found it.
