Wrench and check engine light from switching to a lower tune?

[8luggin]

I was running the 275 tune on my dashdaq daily well just fooling around I put it back on the 210 dpf off tune and the wrench light and check engine came on. Did it come on because the egr sensor is unplugged being it was deleted.

Here's the codes
P1335
P0405

Egr valve codes, can be from being disconnected and/or no flow of exhaust gasses are being seen

You can get the updated Spartan tunes for an egr delete so you can run all the tunes with no codes.
