Turn off the egr?

I just heard something that made me wonder what the difference is between a tune the shuts off the EGR and a tune that Cycles the egr? Anybody know anything about that?

you want to cycle the egr unless you never plan on going back to stock. if shut off completely for more then a few thousand miles it will get stuck. so if you go back to stock your pickup wont really run with a stuck egr valve

Got Mike at KEM to make a tune that will cycle the EGR at idle.

So it it a bad or good thing. I would think if anyone needed to go back to stock this could be a problem? If it does get stuck.

The Spartan system has tunes that cycle the EGR.

Is the tune compromised in any way by cycling rather than just turning it off?

The EGR only cycles at idle, so that the system doesn't get clogged-up and become totally non-functional, in case you need to return the truck to stock for warranty repair.

The EGR does not operate when you are running down the road.

The "tune" is not compromised in any way and the "cycling" at idle is actually a function of the tune.
