Thanks Bill. So would I be correct in summarising that the general message for us S3's owners that are APY non-esp & non-wideband, is that we can stick on the 3' TIP and larger cone filter without needing to change the map. We should see roughly an increase from about 250bhp to 270bhp if we are on stage one, and we shouldn't see any problems with fueling?
If we were to see any problems, in laymans terms
what problems would we see and what would need doing rectify the problem? Is it just that non-wideband cars may not be getting enough fuel to match the increased air and the map needs to be updated to add more fuel? What would happen if enough fuel was not being provided?
What are afr's? Will we be able to do some logging in VAG-COM to make sure that everything is ok, rather than putting it on a dyno?
What's the difference between wideband and non-wideband? From message I read, I thought it meant cars with wideband would adjust their fuel to match the airflow. But you mentioned earlier that on non-wideband cars, initial fueling is load based off airflow... more air, more fuel (stock k04) - so that sounds like non-wideband cars also adjust fueling based on airflow? Confused now!
