What all mods are on the truck? Anything other than edge?

If you take the edge off does it still read high egt #'s . could be a problem with the edge it not uncommon.

Default still tryin

i took out the edge today no change in egt temp.if my stock egr system is f'd would that do it? i read that it cools combustion temp by upto 500 degrees..i doubt it.well its either the turbo vane controller solenoid or the turbo vane position sensor... i think, any thoughts on this? the turbo seems to really kick in and out above 20psi very abruptly and noisy!
