EGR

[BMF_Powerstroke]

I was reading up on the H&S Minni Max and it states that it will allow you to disable the EGR. With that, is it necessary to install an EGR Delete or is it safe to disable it with the programmer long term?

The tune alone will not allow the EGR valve to function properly but to will still have hit exhaust gas coming in contact with your engine coolant which is a no no.
IMO I would eventually get a full EGR delete down the road. That way you know for sure that all the EGR crap is for sure gone and your engine will be breathing the cleanest air it can.

Some people do run it long term with no issues but like mazsecond said you are better off to get rid of the coolers just to be safe if you are disabling them anyways. If one of the coolers does rupture, there is a possibility of coolant entering the cylinders when the engine is shut off & you could then hydrolock your engine.

Turning it off is fine if your truck is still in warranty, but as soon as you are out of warranty it is smart to delete it, if not sooner. The sooner the better to avoid future issues. These trucks EGR's arent as bad as the 6.0, but they arent good.

I didn't think of it in that perspective but, makes sense. I already have the EGR Delete waiting for me to return home to install. I stumbled across the EGR part of my tuner just reading up on it and was curious. This is my first diesel so, I'm learning. Thanks for the clarification guys!!!!
