Any help with tuning idle for long tubes? Having issues finding good reads
Long tubes shouldnt have thrown your idle off, sure u dont have a leak?
They will throw you off based on a wideband readings since they are downstream further. You need to adjust the o2 sensor data, but honestly most don't and just leave it. Otherwise, yes you have a leak an unmetered air situation happening.

I?ve read the long thread about the o2 adjustments but I haven?t been able to tell what was improving what or not. When reading thread, the middle pages, it looked like a bunch of people trying different things and then nothing.
I went through everything and sealed it with copper rtv. It?s def sealed up now. It?s just not sounding as clean as it did stock. There?s def a cough in there at a hot idle

Let?s start with where the trims should be while idling?
What is your hot idle spark advance?
Have any logs?

Did you remove your spark plugs during the header install?
I hear ya. I pull the plugs but know a lot of people don?t and then go nuts diagnosing issues after install.
Appreciate the help. I did open the gap from .040 to .045 on a oem plug tho. Didn?t notice much change. Maybe gets me a hp or two

Fuel trims of +- 5 are nothing. As fuel ethanol content varies, o2 sensors age, it will move around a bit
