As many of you know, I am running my S3 on a Stage 1 map currently, which has been upped to max limits. Boost is at max level, as is timing with a further 3.750 degrees on top. Fitted an MBC to bring the boost up to the level I wanted it at - around 22 PSI. Adding to that, I have recently fitted a downpipe and decat to it. I was getting good airflow figures before the downpipe at around 210 g/s. However, since changing the downpipe, I am getting g/s figures of between 225 and 230. I think now I have come to the limits of the Stage 1 map to be fair. The other day VAG COM gave me a fault code of Air Flow Upper Limit Exceeded. Presumably that means that it is now in fact off the map's tables. Today I have a new an interesting fault code of '17743 Engine torque monitoring control limit exceeded' meaning again presumably that the torque has surpassed expected tolerances. The concern being that my TIP is cavitating, and I need a silicone one really badly. However that will potentially increase air flow even more. Good in some ways, bad in others. / What figures are people getting from Revo Stage 2 cars air flow wise?
