Does anyone have experience related to a grille swaps impact on coolant temps on a c7 equipped with a Procharger and the air to air inter Cooler?

Also have a procharger and want to know, though, I REALLY doubt this changes much...
At speed you have some serious air pressure up front.

I have no hard scientific data, but yes, it was a noticeable improvement. The engine & oil temps run cooler, the engine takes longer to warm up in cool weather, and highway MPG is impacted (more cooling = more aero drag).
