I am having same issue. When pulling trailer with street tune, I have no issues. Coolant sits around 200*. When pulling trailer with tow tune, I puke coolant. I don't know what the pressure is, but my next test is going to tow in stock tune and see what happens. I have studs and if towing stock stops the puking, that seems to be the cheapest method to fix the problem!

Troy, if your coolant system really is (gauge is correct) overpressurizing, the most likely culprits are the EGR cooler (if you have one) or headgaskets. Some say they can pinpoint which is the problem by watching the pressure gauges behavior or watching bubbles in a bottle hooked to the degas line but in my opinion those things can be deceiving. If you pull the EGR valve and it's wet inside the intake and on the valve the EGR cooler is suspect, if it's dry in there suspect head gaskets. This isn't 100% either as you may have to make a judgement call on what is wet with coolant or oily from CCV deposits. Of course if you have deleted the EGR cooler...

going ahead and installing studs and doing the head gaskets. etc etc. has anyone ever used that lifting plate that goes where the turbo mounts?

I believe it would work just fine to put a gauge on the filter housing to monitor cooling system pressure. Pressure should be the same throughout the system. I've though a little "nickel gauge" like they use on aircraft screwed right into the housing would look cool and be handy. I haven't ran across one that reads that low yet tho.

Pressure should be the same anywhere in a closed cooling system. Also if your hitting 18 psi your degas cap isn't working properly. 16 psi max.
