Emissions?
There is still conditional pass with $450 limit. Find a place that will diagnose it for $100 and if the required repair puts you over $450 you're done. Keep in mind the new test limits are higher and no more nox to worry about. Set your idle to 1150 (1200 max allowed), put lots of timing in it and lean it out 16:1 is not out of the question.
The thought of 16:1 under throttle and maintained for a few seconds is scary...
So if there is no Nox, what are they testing? Hc and what?
Would the old trick of adding methanol I think it is? To the gas work/help?
The info on the drive clean site is so vague...

Im wondering if going too lean will throw the readings off.....some of the criteria is excessively too lean/rich condition.
Thats not true. You get your car tested then you have to show you made attempts to fix it. The place will want to see the repairs done or have the repairs done by them. So you still need to have repairs/bills showing they are done AND it must be done at an accredited facility....ding ding ding...money grab.

With a cammed engine the oxygen sensors get confused and the pcm corrects rich. Leaning it out will make it a lot cleaner out the tailpipe.

For a condtional you have to have the work done at a drive clean place yes but they have to diagnose the failure and if the repair puts you over the limit then you don't have to do it. Go price a factory catalytic converter.........you need to find someone that isn't gonna nickel and dime you right to $449.99.

ok, here's an odd thought...what would happen if you changed the exhaust setup to a true dual setup with no X or H-pipe crossing over...run only the passenger side the rear of the car for the test (so they believe it's a single exhaust)...this way the sniffer is only actually seeing 4 cylinders, or 3 cylinders if it's a v6...should that not produce only half the emissions?
Would you run into the problem of the machine rejecting it due to dilution? I wouldn't think so? to my understanding the dilution happens due to Oxygen being introduced no?

It just might work though.
You could possibly have the readings change and create a too lean/rich condition and cause you to fail since it wont be seeing everything. Possibly.

i'd rather get the parts car and swap the vin's....literally the only thing that hasn't been changed on my car is probably the rear hatch glass...do you know how much of a PITA it would be to swap all suspension, rear end, motor/tranny, restart all the weight reduction, redo the brake lines to delete the b.s craptastic abs...etc etc...What a gongshow
Will a car pass with a Air Pump code ? I want to run the test before I turbo this car.
I remember reading something about de-activating emission systems with HPtuners and I won't show as a failure.

If you turn off the proper codes in hp tuner you wont get an ses light (if that's what you ment" done it on mine.
My turbo car has no emission equipement. I'd like to be able to get a pass.
They also look for a "status ready" in the scanner. I don't know if AIR pump is part of the emissions readiness in OBD2... If it is, clearing the SES will not have the desired result- if status not ready comes up, they will not even bother to test.
That being said, the testing has been changed, again (!), to allow a couple of status not ready as long as SES in not illuminated. Call drive clean 1-800#, get the info and go to the testing facility. My experience has been that the testing facilities are NOT really aware of all the ins/outside of this stuff, they're good at processing credit cards that's about it.

If you just turn the sensors off I believe it will show up as "not ready" although I think this varies for different cars.
