Default 04 powerstroke

Have a 04 powerstoke with 125k on it. Runs down the road great. Cold air intake on it. Muffler delete and cat delete.. I hooked up to a trailer with my jeep on it and found out I have no the best of power towing.. This truck did not come with a boost gauge.. So I added one.. If I get on it with out a trailer I get over 20 psi of boost. Driving 70 down the road I am at 7-8 psi.. If I put my trailer on it. Get on the highway it will go to about 40psi.. Egr is clean I pulled it.. Cleaned and put it back in.. I should have a ton of power and boost shouldn't be that high.. I don't want to blow something... And ideas what can be wrong here?? Info on this would be very nice.. I did check all the boots.. Replace the one at the turbo. But still the same.. ??????? Plus i have seen that my mpg have gone way down too..
