i was pulling my trailer up a hill and it ran just fine up it like it always does and when i got to the top it was downhill so i let off and the wastegate seemed like it was stuck open then i got to my house and parked it after a few hours i went to leave again and it was only making like 5 pounds of boost went i got on it and my egts were really high i looked back and it wasnt blowing smoke or anything so i dont know if my turbo went out or my wastegate is messed up or something else any help is appreciated thanks in advance

 

check for boost leaks.

 

test the waste gate operation by removing the hose and blowing shop air. I had to free up my waste gate a while back, using vise grips, penetrating oil and a thousand cycles of shop air!

 

Turbomar, can you explain this process in detail? I think this might be the problem I'm having. Thanks.
