I recently installed the Gen 2 Cobb LF BPV onto my car, and I have been experiencing problems with my car, such as getting a p0171, which is a code for running too lean. I was wondering how to correctly adjust the BPV, since it is different from the Gen 1, where you just use an allen wrench. I have a 2008 LGT, with the cobb stage 1 ots, and a nameless axleback muffler delete. This code popped up after I installed the BPV. This code only pops up when im idling. Thank you in advance.
