EGR delete w/tune?

Can you do a EGR delete with a tune that will just shut off the valve so your not dumping trash down the intake?

Many custom tunes shut the egr valve off. High back pressure can forge it open still. I've been told the valve should stay intact as it controls the fan clutch while towing.

Yes you can turn it off. But at the same time you still have coolant and exhaust flowing through the cooler so the cooler can still possibly fail on you.

You will only have exhaust flowing through the cooler if the valve is forced open as Teachamech states above. If the valve is closed it is blocking off the engine side of the egr system. But yes you still have hot gas in the egr cooler and it can still fail on you. It is best to delete it if you can. If you can't a BPD cooler and turning it off in the tune is the next best thing.

My next step would be to either weld up the cooler on the up pipe side(both would be better) or use a block off plate(there's some discussion on this in other threads). The really important thing is to remove the scoop in the up pipe(05-07) so the exhaust gasses can flow freely to the turbo.
I live in CA so we have emissions testing... So I have to appear as though the egr system is intact. :what:

Well I found on my SCT were I could do just what I asked so I did indeed turn it off. I will go ahead and to the total delete next time Im in their but for now its all good. I dont have any thoughts that the cooler will fail being its basicly new and Bullet Proof.
