Is my 6.5 grendel over gassed

That is unusual. QL tells me that you should be 50fps higher with CFE than 8208 at max SAAMI with your COAL and barrel length. I suspect either a chrony fault or your two loads are not at equal peak pressures. Your 32.5 CFE load is definitely going to hammer your gun. It is also 104% of the available case volume which is getting into compressed load territory.

How many grains of 8208 are you loading?
