So I purchased DRD tuning and seriously can’t thank them enough from my first question to shipping notification was <2 hours.

My question is I’m using it to delete def system (due to service def message, 85 miles to limp mode) and delete egr but keep it intact.

I imagine it’s also going to tune out the DPF getting rid of Regens.

I do not have a delete pipe and need to drive the truck this weekend.

Is it safe to do so with the DPF still intact?
