If you remove the bumper, the temps stay at a constant 190F which indiciates that there's way too much heat being generated.

I'm experiencing this issue as well. I opened a few discreet holes with a hole saw in my bumper and I'm running at about 227-228 degrees on my coolant temps after pulls. I've been running around 220 degrees when cruising. Last night I opened up two more not-so-discreet holes with ducts to either side of the Nissan logo. I'm not a huge fan of the look. I haven't tested yet, but I'm hoping this will bring the temps down some at least. If not, I'm going with a Stillen bumper and vented hood.
