2014 Si TUNE PLS HLP!
I recently picked up a 14 si and it’s desperately in need of a better basemap. It has a cat less dp, rbc, generic Sri, invidia n1 exhaust. It keeps throwing a P0171 lean on bank 1 code. It drives rough under throttle as well. I’m not looking to do any further mods. I just want it to run good and strong. If anyone could help point me in the right direction, I’d be forever in your debt. Thanks in advance!
