That or a tune, but if you threw all that on the car, you could definately benefit from a tune anyways; Mail order or dyno.

O2 Simms are crap, that number one!

2nd they do nothing to the computer to remove anything. They are supposed to give back a false signal of what the down stream O2 readings and supposedly will trick the PCM in thinking stuff is ok.

Your better off having them turned off. That will elimiate all your issues.
