if your running canned tunes thats gonna be part of the problem
I doubt he has any boost leaks as he is hitting 21-23psi. That's spot on for a stock truck at wot.
Run it on the 30hp tow tune. That 75 tow tune is probably for under 6k pounds.
IIRC, a stock e99 is not rated to pull 14k. Only 10k. Especially going up steep hills. Get rid of the muffler too. Or just get the 4"T/B and a 6637. Together they will help around 150*
