P0171 & P0174 i just switched cams and added heads and injectors and now my car is throwing these two codes. i have done some logging and the l trims are peaking at 25 in most of the histograms. when i had my old cam in my tune was dead nuts on. i have tried to tweak it but the l trims are still out of wack. any ideas?
