random boost issue
hey i have read this post a few times from people on here but they never got answers, and the last post was almost 6 months ago, so i figured i would ask again.
i have an 01 a4tqm with apr 1 93 chip, apr tip, intake, exhaust and i put a labree hf cat on it 3 days ago.
this problem was random before, but now it happen to switch three times on a trip i made today. it will boost normal 1 bar, but then out of no where it will only boost stock, and after driving awhile or letting the car sit off for a bit it will be back to aftermarket. but now it just through a code p0171 car running lean bank 1. i erased it and the psi went from stock to aftermarket immediately (i did this cause someone said it worked randomly for them but not a long term solution).
has anyone else had and solved this problem? could it be related to the N80? because i think i can hear my clicking.....
thanks for any help.
