Just bought a 06 V8
 

Any tweaks for better mpg

have 06 V8...changed all O2 sensors..and K&N filters..bout all you can do except keep your foot out of it....both made a difference and also seat of your pants ..and the filters really let the engine breathe you can feel and hear it..everyone always asks if it has after market exhaust..does sound great

i'd love to take your car out for a spin. i'm sure you get alot of compliments. what kind of mileage do you get now that you've made the adjustments to your touareg?
