IMHO you will always have EGT problems while towing if you do not upgrade the cooler, and delete the cat and free up the exhaust and use much higher boost. I dont really know the effect of EGR delete as I deleted mine before I had the mods.
Even then I have to watch the EGT gauge closely all the time on hills to hold it under 700C with occasional 750C using about 22Lbs boost.
So it becomes a balance of speed loss vs acceptable EGT, although the car has much more torque on hills.
I have an old BAS tune and while it is good without a trailer on, I have to closely monitor EGTs when towing my 1000Kg loaded camper. It was much worse when I towed my daughters 1500Kg camper.
I can rarely use cruise control when towing as it rams the throttle wide open at any loss of speed.
