I have a 2006 Passat 2.0T... I've added a Neuspeed ColdAir Intake and a Catback MagnaFlow exhaust. Car sounds great by the way!!
My problem now is that i've noticed the vehicle fuel consumption has increased now and many have told me to "Flash the ECU"
Some are telling me to do a stage I, some are telling me to do a Stage II... I've done some reading on my own and now my brain is all confused?!?!?
Feedback is appreciated!
