That should also eliminate it as a source for the puking. I'd be thinking about head studs.
EGR cooler deleted and brand new oil cooler also done. It only did it when towing and and temps made a spike. When there is no load I never have an issue. Even when I am hard on it. You know like Mario Andriette. The coolant level was also in between MIN and MAX so with the higher temps and expansion I would assume this is what was causing this.

I agree with this. The level was a little high. When I had the oil cooler done the tech told me right up front it will most like spit some coolant if its a little over full. It did that. I just think it was still too much coolant for the added expansion from the increased temps.
HG still check out good and oil is clean so no studs yet.
Thanks guys for the feed back. Seems to be right in line with what people are seeing for temps when towing.
