i have a 2005 passat tdi and i was wondering what first performance stuff i should do to it first. exhaust , chip, turbo. I love how fast it goes and the MPGs.

 

Start with a good Air Intake , maybe even a drop in filter

 

wouldnt that cause problems with the maf?

 

most of the vehicles that need that,the CAI companies make em so you can hook stuff back up that needs hooked up for the vehicle to run properly

 

threads been dead for a while i see, but my wife just bought an 05 and i can see that the factory air intake has a pipe to the grille above he fan housing and there is a spot that looks like somebody at the factory wanted to cut little fins in the top of the grille and never got to it so im gonna grind the back side of the grill out and open up that spot so the motor gets fresh air, best part is the hood overhangs enough that unless the hoods up you cant see it
