I need help... just put a turbo on my 2000 5.7 tahoe, new tune came in and ran great! no issues for over 100 miles. put the trailer on and pulled a few hills hard and drove aroud awile(45 miles). thought i was good to go......... i left for vacation today. got about 50 miles away i was running warm but not any hoter than I ran towing without the turbo on a hot day about 200~210. anyway pulled over to do a quick check on the trailer... merging back onto the highway it woud not pull past 3000 rpm. limped it to my folks house and no codes. unhooked the tralier pulls hard through first (with a little hesitation aroud 3k) shifs hard into second but limmits out a 3k...
where do i start ? no codes, plugs look good, Wb reads good plenty of fuel

 

loose charge pipe after MAS letting just enough air out to make me run too rich
