Have a custom tune on my 2006 Jeep srt8. Smog test came back rejected. I disconnected the battery to reset the adaptives but that was months ago. Do I need to just put the stock tune back on to pass or what should I do. Need help asap. Thanks everyone.

you need to put the stock tune back on.

then you need to drive a bit to reset the adaptives and get the o2 back to ready.

then if no cel, then e-test.

if cel, then ............. get code cleared.
