Not totally familiar with Dodge stuff but in general pre turbo EGT's should stay well below 1400 for sustained pulls.
I do sustained pulls at 1250, I back out at 1300. When I'm playing with higher power levels I can see 1600+. I have been there a few times for less than three to five seconds eash time. Truck seems to be surviving well, I lifted the heads a few years ago so I put new head gaskets on and everything looked great in the cylinders and heads.
Lowering EGT is simple but can get expensive. Air in air out. Big intake, big exhaust, good intercooler, good tuning, then you have turbo upgrades.
I tow with my 05' D max and quit adding power a few years ago. For the loads I pull with my truck a simple 85 horse predator tune, boost controler, intake, exhaust and gauges have me where I want to be. I put 2500lbs in the bed and tow the race car with no problems.
I would look at air in air out upgrades, I don't see the turbo work as good until you deal with the intake and exhaust.
