so i now own vcds and love it, i just read on hear to check the adaptation mixture in block 32, and also hold the revs at 3000 rpm and the air flow should be 10.00g/s, so off i went and had a look at block 32. it let it run for 5 minuets as i think i accidently reset it, the idle one was showing 0.4% and the other on 0.0% and the same after 10 mins or so. i then tried to hold as best as i could at 3000rpm but the air flow only went to about 9.00 g/s maybe even just below that. my car is a 2003 aum 1.8t a3, 120k miles with no fault codes. how ever when on boost scince i have owned the car you can hear quite a loud ssssssssssssssssss, but like i say no noticeable loss in power however has allways been there and been checked by a couple of people for leaks but none found however never had a smoke test. just information on what to do next really as i want to start modding car but want a healthy engine first. thankyou..
