Failed inspection

[Stealth]

Still nothing. Anyone care to take a stab at this?

The only thing I can think of is doing a battery disconnect(with the tune loaded and programmer disconnected, then hook up the programmer after the battery is reconnected) and completing a drive cycle again....something in the EVAP system might be the issue.....Bill omits the p1000 but none of the other drive cycle tests are omitted...

I'm not showing any codes stored on the tuner. Before the tune adjustmest and after the header install I got a couple of cat inefficiency codes with a light on the dash. I had bill adjust the tune to turn off. The rear o2's so the codes wouldn't come up. Since I knew the cats were small I put on the larger magnaflow cats. Never had an issue before with inspections and bills tunes. So will I be ok setting to stock for the inspection after drive cycles???

Just leave the custom tune loaded.....reset pcm....do the drive cycles....

your programmer cannot read if the tests have cleared...there's another scan tool for that....

I'll try. Hope it works. I can't afford another $40 for inspection being out if work right now.

The codes that I had were p0420 and p0430. Bill adjusted the tune to turn off the rear o2's so these codes wouldn't arise. After he did that the codes never came back. Fast forward six months to now and I have better cats and the cayalysts and o2's read not ready on the inspection report. This is why I believe the rears were not turned off in the tune properly. It is my opinion that returning to stock would be my best bet vs trying the same tune again. Opinions? I need an answer soon. lol
