i got a 2001 cummins 24 valve. for the last 2 week it has been sluggish on the take off but after it reached about 1700rpm it would build up presure and then it would have power. i decided to check the wast gate and see if it was opening and its working fine but now all of asudden it has no boost presure. it wont even rech 30mph. i cheched the map sensor and wat i think is the boost sensor and cleaned them both. but my truck is still throwin a 237 and a 113 code. anyone have a clue where to go next?

 

Check or boost leaks is my first thought.
•Make sure everything's tight
•Spray soapy water on intercooler boots and look for bubbles (turbo too)
•Go with the least expencive solution first
Best of luck and I don't know anything about those codes. By this may help
