Kris can better answer the code question...
Regarding the hole-- Yes, it comes with temp sensor. This way you can retard timing as your intake temps climb and importantly, post blower. Since you want to be able to pull timing as you see those blower temps climb so you have the most power you can get at all times and still be safe as the temps fly through the roof on the highway and at the track...
Best,
Phil
