What is the underboost problem and how did you diagnose it?

Hi Drew, I believe that I may have a similar problem with my Octy 1.4 TSi - can you describe the symptoms you were getting?

Hey Phil, did you ever take the plunge and buy yourself an uprated exhaust?

Hi Phil, as it happens I have been considering the answer to the exact same question. And I think I may have found a solution for both of us! https://www.fox-sportauspuff.de/ Their catalogue seems to cater for the 1.4 TSI, I have a 2011 Octy Estate. I've chipped it using the Superchips Bluefin and installed a K&N filter inside the airbox but I think that the breathing is pretty restricted by the OEM exhaust. FOX appear to do two different centre sections, one without the centre box! I've discovered that these are available here: https://www.dcperformance.co.uk/cheapest/fox.html Are you actually based in Germany as per your user profile?

Agreed, love the Octavia II shape especially in facelift trim. I've just purchased myself a very similar 2011 Octy 1.4T SE Plus Estate in black - will post some pictures when I've picked her up!
