EGR problem?

[kingranch25]

Wondering what the problem is with my truck or if there even is a problem before I take it into the Ford place.
Problems:
Some white smoke on start up and sometimes when I floor it.
EOT and ECT is anywhere from 15 to 25 degrees difference but sometimes between 10-15 degrees.
On my edge insight, mostly after I floor it, the boost stays at 0 even when I am driving.
Truck has lost a little power but still hits it when I want it to.
I am thinking it is the EGR and oil cooler but one day the truck seems fine and the next I'm wanting to take it in to Ford place.
Any insight would be greatly appreciated, thanks.

Also, I am about to do the EGR delete, studs, gasket so I am not sure if I should get it fixed first and then do egr delete and stuff or what because the ford people told me they will not put on any "performance" stuff.

Your stock oil cooler is blocked, and not flowing coolant. This leads to added heat and stress on the EGR cooler, and soon a ruptured EGR cooler. White smoke in the exhaust is the start of a leaking EGR cooler, when it actually ruptures, people behind you will be blinded like a James Bond smoke screen (not kidding either). You likely have no head gasket issues, but if you do not get the stock oil cooler out of your truck, you will. Do an EGR delete, and I would seriously recommend an aftermarket oil cooler, unless you want to do this every 50k or so.
