Tolerance of water pump play?

So if i have no issues with overheating now i certainly should not have any problems with the high flow pump and t stat in theory right? Also the high flow pump states it increases coolant pressure, do i need to be concerned with it causing leaks due to the increase in pressure?

The pump and stat should not create an issue, they are better than what's in there now.
I don't see how it can increase the operating pressure, the cap is in charge of that. I run a 7 psi cap, cuz like you, I have no overheating issues,ever. And the low-pressure cap is easy on the system. But Unlike you, up here we only have a few days a summer that the temp gets over 85, and fewer yet over 90*F. And like maybe one or two over 95*,lol.
