My 01 2500 starts cutting out ( like a miss fire if that's what you call it) above 2k rpm. I have all my settings on my quad turned up high to see if it is the problem. No luck. After it does it the quad beeps and says defueling. When it did it this morning egt=770 boost= 10

Sounds like a lift pump problem

 

yep like ed said sounds like a fuel pressure issue, going to have to check that out

 

I don't have a fp gauge but I have a brand new raptor on it. It is running but I guess that means nothing without a gauge.

Have you downloaded a different program to the quad? Them things can be finicky. And I would also put a gauge on it to see what fuel pressure is. They make an fp adapter for the adren

 

It has factory tune but I did turn timing down to 7* seems to help keep egts lower. And a fp gauge is in near future

I would try a different tune and see how it runs
