FAILED Texas Inspection (BM3 Stage 2/Catless DPs)
Like the title says, I went to have my annual TX state inspection done, and it failed!
You're only allowed one "not ready" and I had three. Trying to find out what my options are. I'm running a custom BM3 stage 2 tune + VRSF catless DPs. Thanks in advance!

What about the BM3 tune? Can I leave that as-is (ie, stage 2) or do I need to flash it back to stock? Thanks!

The lack of cats is the reason why you are failing emissions. That's their job. The tune at idle should not cause any issues. Some states also connect to your OBDII connection to read data. Some can detect a tune, so going back to stock is a good idea. The fact that you've already failed they may pay closer attention.l to your car.

Priceless 😅 Either get a tune that makes your cats show ready or swap back to stock, conduct a drive cycle to make sure your checks are ready then return back to the shop.
Sounds like you might be in over your head. Best to get an OBD2 reader so you can check your status before arriving to the shop.

OR...consider getting race-catted DPs and/or spacers to move your lambda-probes back far enough to not be in the exhaust mainstream.

Thanks for the advice guys!
I'll have the OEM DPs put back on, and then back to the VRSF DPs after passing inspection...
