Hey everyone, I was recently told that I have to take my car in for smog testing. I have a JLT CAI and a custom tune from Brooksspeed in my car, and I wanted to know, do I need to take out and replace the JLT and the custom tune with the stock intake and stock tune before I take it in? Or will the JLT with the custom tune pass?

Thanks :bigthumbsup

From what I was told when I had the same situation, is that your O2s are turned off in the tune and wont pass emmissions testing. So for your smog test I would go in stock. Just drive it 60-100 miles to reset the sensors.

Or just reach out to Brookspeed and ask for an emissions tune for your JLT. The good tuners like Brookspeed can write a tune that re-enables your rear O2 sensors to pass emissions.

Contacted Brooksspeed. Hopefully they can make me an emissions tune for the JLT.

As stated several times.. It depends on if the tuner turned off the rear 02 sensors or not.

I asked Eric Brooks, and he said my O2s are still on in the tune he gave me. So does this mean my car should pass fine, or is there anything else I need to check?

It should pass fine. Man i love these threads, it makes me smile that much more knowing i live in a state with no emissions lol.
