but my question is whether or not a 4 speed manual would out-perform (in mileage and performance) the stock 4 speed automatic that is in my 3.0T.

Also where can i get higher gears for my diff? and how do you make the adjustment to the speedo? are they like older cars where they have nylon gears you can swap out for different ratios? by the way, within the past couple of months i have rebuilt and pop tested my injectors (monark nozzles), adjusted my valve clearance to spec, adjusted my injector pump and advanced it to 28*, added a custom intake/filter system, removed my EGR, Switched to 5w-40 full synthetic oil, and i put my ALDA back on and tuned it way down.
