EGR delete

[Berge9798]

I have a 08 that i have been doing a little work to. DPF/cat delete, 4 inch down pipe, intake, egr block and water meth. i have the edge evolution at the time but i have a H and s tuner on the way. i have been reading a little about the egr and have realized that the block is not the right thing to have because of the waist gate being part of the egr. I was wondering what other people have been doing about it?

There is no wastegate on the 6.4, BUT the EGR valve does act as a pressure relief and keeps the back pressure to boost ratio close to 1:1 (which is want you want it to be close to). The only alternative is to do a full EGR delete w/wastegate. Not having the plates in will allow for some of the pressure to bleed off, even when the EGR valve is shut off with tuning. The plates allows ZERO back pressure to be relieved.

Agreed;

The wastegate is the best solution for this, unfortunately cab removal is required to install it, and if you need to ever return your truck to stock, it's a LOT of work.

I'd be interested to know if someone could make a wastegate work on a street application, and put it at the EGR cooler inlet on the horizontal cooler -- and just dump the exhaust to the atmosphere. Yeah, it'd be loud, but a hell of a lot easier to install/remove.
