ACS Upgrade + new temp probe.

I upgraded my YS480 to the ACS controller and replaced my temp probe while I was at it as it was broken.
After I got everything installed and fired up, the two external probes have a 35 deg offset to my Pit probe.
The PIT probe is INCORRECT vs the external probes, I verified it with a my normal pit vs food monitor I used to use.
I know I can do a calibration (Read the posts) but good lord, this offset is massive. I am starting to think my new probe is Dead on Arrival..
Anyone else see an offset this big before between pit and external probes on the acs?
