Long story short, my 03 will not pass emissions although it has passed all prior years up to this year. Supercharged, no cats and cams. Car has a new tune due to the cam install. Was told there is nothing in the tune that would keep it from passing. Az requires 4 of the 5 monitors to read to pass. Both catalyst and EGR monitors are not ready even though I have driven the car close to 600 miles in every driving situation possible so I have met all drive cycles. I have even gone so far as putting the stock H pipe back in. Anyone out there that can help? Car has been sitting for 3 months and can't even enjoy it due to this.

I live in Sierra Vista; we don't do emissions testing down here.

Cats not ready either wire problem or not up to temp. EGR might not ever show up as pass as some vehicles its a NA test.

Cats have never read, but EGR has always been good. Only recently have both not set. Started after a cam install and new tune. According to state regs I need one or the other to set in order to pass. All other 3 monitors are good to go.

some tunes require to be reset to factory in order to pass emissions. Is this your case? However, this could cause other issues, i.e. a CAI that would otherwise throw codes if a tune isn't done.

My 05 passed with flying colors however, all I have is Cat Back's and a Air-Raid CAI without the vent and no tune.

We might be moving to the outskirts of the Tucson area. Possibly Catalina area.

Do they have emissions testing there?
