Hello everyone, I have a 2004 Mk1 TT 225 and I recently put a new turbo inlet pipe, and a new air cone on. Now my car is getting no boost and I can’t figure out why. A while back I put an air cone on with my stock intake and it did the same thing. Then when I put my stock airbox back on it worked fine. With a stock airbox it runs fine, therefore I know nothing is “broke” but possibly misreading due to more air than usual. Which makes me think it’s either MAF or Throttle Body. Check engine light is on for o2 sensor. But I’m not very experienced with VW so I’m not sure the exact issue. Any help would be appreciated, thank you!
