No problem.Sorry if i sounded crude.didnt mean to.get back to us with your findings on that code and maybe it may be related to the tune but it could also be coincidental.O something coverd up by a previous tune..

That makes a bit of since as far as covered up from previous tune. I'm at work till close so autozone is out of the question till tomorrow. But I will be updating.

Drum roll please..... p0420 is the code and if I'm not mistaken. That'* 02 sensor. Now I no that that was turned off during this tune. And I don't think this is effecting the runability. If the hi Flo cat does not have use for the o2 should it be unplug?

That code is labeled as catalyst low efficiency, Looks like I missed that code. Plugging the sensor back in will take care of that.

But there is no place for it to go in the cat now. Do you mean just plug it in and leave it secured to something or do I need to drill out something.
