EGR Delete without tune, what happens?

[mulletator]

Hey guys, my '06 CRD is at the mechanic right now to have the exhaust manifold repaired. I'm also having them do an EGR delete. I have a kit for that.

They won't be able to tune it though. It will be a while before I'll have time to do the tune.

Can I drive the Jeep normally with the EGR deleted and no tune? I'm sure there will be a CEL but will it actually affect the running of the engine? I don't really care about a CEL as long as it runs fine.

It should be fine without a tune, and happier, and cleaner inside, and introducing less abrasive crud inside the engine. Will probably have a check engine light.
