i have a code P0174 (means bank 2 lean). my question is (by the way i have a 99 SVT) bank 2 is the down stream? or is there a O2 on each manifold? i ordered a mil eliminator because i thought bank 2 would be the down stream which wouldnt matter performance wise. but is that right? i figured why spend $ on an O2 when i can basically mimick it w/o performance loss. the only engine mods to the car is resonator delete, and fabbed K+N intake. it shouldnt be lean right? any help would be great. PS put a Fidanza flywheel in the other day and the car only went .04 tenths faster in the 1/4, and picked up no mph. what up? weather was about the same as was car temp. and 60ft.
