Question EGR Delet or not

Ok , well I have read lots of posts on the search feature and still wondering whats the best way to go. Getting Mini Max next week and plan on doing dpf and cat delet, I know you can turn off the egr with the mini max, but did not know if that was the best way to go. Some of the guys around here are saying to just shut it off and it will be fine.Truck is a 2010 f250 w/ 60k miles. I live in east tx so not worried too much about inspection of emmisions equipment. Just want better fuel mileage and more go////

Look for pictures of how clogged the intake elbow and intake are. At the very least you're going to want to replace the elbow... which means you might as well delete the coolers as well.

This is pretty much the opposite of what causes most people to decide to do this (most want to get rid of the EGR coolers and later decided on the elbow).

That is most likely what I am going to do sometime. Delete coolers but wait to do the elbow and CAC pipe.

I'm curious why those that need to keep their EGR coolers in place for warranty and emissions testing do not make a kit which blocks the exhaust at the entrance of the lower cooler?

Could you not loosen the joint at the exhaust manifold, loosen the straps on the horizontal cooler and then squeeze in a 8 or 10 gage block off plate and re-tighten the bolts? That would deadhead the exhaust in the manifold AND the biggest benefit - not allow any possible EGR coolant leaks to flow back thru the exhaust manifold and into the engine. You would continue to flow coolant thru the coolers, but since they don't have hot exhaust blowing thru them, the possibility of cracking due to thermal shock is eliminated. Then once it's time to go back to stock for whatever reason....swap out the intake elbow with the OEM EGR valve and remove the block-off plate from inbetween the exhaust/cooler joint. BHAM......and replace the DPF/DOC....retune....yadda...yadda..yadda....

Sorry to sidetrack the OP's thread....but since we are talking about deleting EGR valves and coolers...thought I'd post.

It might be a little tricky to get the leverage to move the coolers with them connect to each other. I'm sure it could be done, but it would be a pretty big hassle IMO.

The exhaust block off plate for the horizontal cooler is about 6 gauge (it may be 8 gauge), but I didn't measure it.

I think for most people it's easier just to get a tuner and let that shut the EGR and call it a day. You don't even have to spin a wrench to do that.

I got the PTP EGR delete kit which contains about a 1/4" thick block-off plate with thru bolts and nuts to fasten onto the exhaust manifold. I haven't researched "6.4L EGR block-off plates" yet, so I don't know if anything is available. Since I have the PTP plate, I can use it as a template to trace onto the sheetmetal.

I was thinking of making a relatively thin - 10ga which is .134in thick plate. Maybe you are right and I can't wiggle the horizontal cooler forward .135in to get my blocking spacer in there. I would like to try and report back unless someone already has and failed.

All in all - the idea was to put my mind at ease by removing the possibility of an EGR cooler leak hydro-locking a piston in the event of a failure. ....AND keeping them installed for warranty/emission work.
