truck is running rough after LT header install

Is this normal for installing LT headers and not getting the truck tuned. it seems to stumble while driving at low rpm's? the check engine light is not on. this is on the truck in my sig.

You may have exceeded the parameters of a stock tune with all those mods.
Suggest your next mod be a Nelson performance tune. I had same mods 3 yrs ago but had a tune for header install and had no issues.

Or if I plugged up all the spark plug wires! Simple mistake, the back right cylinder was not plugged up all the way.

Cracks are sometimes impossible to see or feel.
