SCT and EGR issue

So I recently just got an egr delete done to my truck. They did the full delete except the shop left me the egr valve in place and still plugged in. I have 2 questions.

1. Is it ok to leave that egr valve in and plugged in like that?

I also have the SCT SF3 to rid of the cel and this is the second question.

2. When plugging in the tuner it asked me if my egr was ON or OFF. Which should I select if my egr valve is still plugged in?

Thanks guys for any help

1. Yes it's ok to leave it plugged in

2. Turn it off on your tuner, but that dosnt mean that you won't throw a cel. Depending on your stratigy you can still trip a p0405 code.

Id look into getting a custom tune that can turn the cel off if/when it does trip

Ok thank you for the reply. I turned it off on the SCT. But the SCT did turn off the cel. Do you think it will come back on shortly?

It's a possiablity that it will come back on but until then I wouldn't worry about it.

Sorry to hijack but had a similar question and didn't want to start a new thread for it.

Just got a SCTt x4 and I still have the stock EGR system in the truck, does it help/hurt to turn the EGR off using the SCT?

Thanks!

It will help prevent or slow down coolant from entering the intake if your EGR cooler would fail. Under high boost levels, the EGR valve can open from the boost pressure.

It won't hurt anything by turning off EGR valve with SCT.

You'll like the custom tune, it's kinda like going from stock to the performance all over again! You will never want to drive it stock again because it will feel like such a DOG!
