These guys are local...my obviously my interest is high as I can just drive there.
We've confirmed that the spark plugs don't need to be gapped, and I can just have them adjust the values on the ECU...correct? I did a tune on my '16 Optima and had to change plugs, gap them, etc, etc and still had pre detonation issues. Ended up $800 in the hole and went back to stock.
I'm still breaking the car in, but looking to do this in a few months...
