Brenspeed and Bama both turn off rear 02s on EVERY tune unless told otherwise. It depends on how your COUNTY does inspections. Inspections aren't even the same across states. Some counties, such as the one I live in hook up a reader to your OBDII port and check your rear 02 sensor readings to see if your cats are working properly. If they are turned off, you fail emissions. I did even with cats. If you have an o/r pipe and the rear 02s on, the CEL comes on and you fail. It all depends on what county you live in and how strict the testing is. Why dont you just go by a testing place and ask them what they test so you can figure out what you need and stop freaking out at Brenspeed.

From Doug at BamaChips:
"This is the reason why tunes may not pass a PCM code read emissions test.
EVERY tune made starting with a base file(SCT or Diablosport) prevents the engine from
doing as many tests as it normally runs in order to speed up the processor. For you
computer guys its kinda like speeding up the clock speed of the processor to gain more
performance from it.
The Ford PCM runs a series of tests called " Readiness Tests" on certain systems and
sensors, and these tests in turn simply tell the PCM if these items are performing up to par.
If not, then a code is set. These are SOME of the tests that are disabled by the tune
files, and this is why when you go to a testing facility with the tunes loaded you may get a
"System Readiness Test Invalid" or "Not run". Not because of the rear 02's being turned off,
but because of the testing for the entire emissions readiness being disabled in the PCM.
Now for the big question, how do we pass testing?
The BEST answer is to simply return your car to the stock tune and the stock intake and
drive it for around 50 miles or 20-30 minutes. This will set all of the " Readiness
Monitors" and allow the car to pass with flying colors, as long as there are no other
issues.
Now we all know that for some of us this just isn't an option, everything from Off-road pipes to CMVC delete plates to Supercharger installations can prevent this. There are ways around this, but for legal reasons I will not publicly announce it. All I will say is that IF
you've gone with a quality dealer or know of a custom tuning dealer to go to, of course
like Bamachips, then we know what to do to make your car pass the PCM readiness tests.
Consult your custom tuning dealer for more information on this.
Also, these tests are different. I've had customers who have reported absolutely no issues
going through their local testing facilities and others who report immediate concerns, like
described above. Either way these tests can be passed with aftermarket components, but
remember this is ONLY the tests that check for codes in the PCM. Tailpipe sniffer tests may
pass, but I cannot guarantee this."
