Hello. I have s3 8l stock. Only s2000 filter. Yesterday i did some vcds logging and something is wrong. There are no fault codes. I tried on 2nd and 3rd gear from 2k RPM till redline and both had same readings. The maf is reaching only 145g/s. Which is ~180 hp, which is not good at all. I tried with maf disconnected, but nothing has changed. Maf readings and power delivery were the same. The car is runing fine. Same as before 1 year when i got it. Request and actual boost are the same so i guess there is no boost leak. On channel 032 the left field was 0.2% ( no air/boost leak i suppose), but the right one was 18%. Fault codes have been cleared a few days ago just to be able to see fuel trim. What does this mean? Also how can i find out if the pre-cat lambda is gone?
