How heavy is the trailer?
Big tires, heavy trailer= high EGTs with stock 3.73 gearing .
Also, not sure how hot those Edges run.....what setting are you in?
Most 7.3 owners prefer a custom tuned multi position chip (DI, TS, DP, BTS, Elite, TW, etc..).

well you sure you dont have boost leak, that 700-1000 sounds little much , i would drop the K&N and look for Soot buildup aroud up pipes and exhaust, downpipe, and the baby Butt in the back of the turbo, common problem if the turbo is replaced and not seated properly , will leak boost and jack up your EGT's

Now that I reread I see you have 4.10 gears?
That should make up for the 35s.
I'd think boost leak or the Edge as well.....

Well that makes sense. The turbo is basically a heat, pressure and velocity powered pump. When you have alot of pressure and velocity, the engine is making heat from the load. The turbo actually uses this heat to spool (and keep spooled) the turbo. The EGTs when the turbo is not "working" should almost be the same, but under a high load it should be alot less, 200-400* difference.
Something You could do is remove the intercooler, run boiling hot soapy water through it, and see how much oil you get out of it. The stock crankcase vent system runs it through the intake, and alot of it settles into the IC. That is a long shot, however worth a try, its free. Clean and dry it very well, and see if that changes anything. If you don't want to change the tuner ( Edge products is very base-level) i'd recommend a Spearco intercooler upgrade from blackwidowdiesel.com
