Question about EGR?????

[03-6.0PSD]

When running the SCT Tuner without the EGR blocked off, is there any problems other then puking out coolant? long term effects, short term effect?

Does it just make a mess? or will it do any sort of damage to the motor if it is not blocked off?

preformance wise, will it effect anything?

this is on an 03 6.0L. I was looking at it today, and I noticed that its not going to be very easy to take the EGR out to put the block off plate in. I will need to have a shop do the work on it. and the shop I talked to today figures a fair bit of work in order to take it out and install the plate.

Thanks for the help!

I think you can have the sct turn off the egr. At least I believe I read that.

Vital,
Yeah, turning off the EGR will only prevent the exhaust gas from going back into the engine, but it won't prevent the exhaust from going into your EGR cooler and flash boiling your coolant and causing the puking... Hence the block off plate.

Any time you add a tuner, programmer or chip, you are borrowing some of the longevity and putting additional stresses and pressures where they weren't specifically designed. With the appropriate precautions (like the EGR block off), you can still do plenty of mods and not hurt your truck...

Oh and you don't need to pull your EGR cooler (I think that's what you mean), you only need to pull your EGR Up pipe. It's not too involved, but something of a PITA... You need to pull your passengers side tire, your exhaust down pipe, and that should give you access to the up pipe.

So, is there a write up or "how-to" pictures of this anywhere on the net?

Yeah, I think I saw it on another forum while investigating it for my truck... I'll look for it now and post it up if I find it.

Keep in mind the 03 - 04 and 05 - 07 6.0L's are different. so what applies to the 05 and up 6.0L to block the EGR off are two different procedures.

[Evil Eye]

Not really, the procedure is really the same, you just have a smaller EGR cooler and different up-pipe. The main difference is the 05 - 07 up pipe has a small deflector inside it to flow the exhaust into the EGR cooler and the 03 and 04's don't.
