2003 Jetta manual.
IQ was 3.8, I adjusted it to 4.8 with adaptation. Nothing changed after intake and intake port cleaning ~10 days ago.
Car has a K&N filter -- which I realized while digging around in there was VERY far past due for a cleaning. OK, I haven't touched it since I got the car(with the filter already installed and dirty) say ... almost 9 years ago.
I cleaned the filter thoroughly including getting all of the old(and mostly solidified) filter oil out this weekend.
I re-oiled and everything still runs fine.
When I checked the IQ, it had shifted from steady 4.8 to 7.8ish. All measurements with the car fully up to temp.
Software adaptation limit is now like 6.5 minimum ... where it was below 3 before.
I assume this is obvious and just comes down to me not understanding how IQ really works and what it means.
Car feels fine and boost logs look OK. Any reason I need to lower that IQ? To do so would require the hammer mod, which I have done in the past.
Thanks!
