RE: Boost pressure related derate (01-16-2023 )Dragonfoot Wrote: 2005 ISX 15, demandated. When boost pressure reaches 34 lb it will derate to 20 lb or less. Comes back slowly in about 20 seconds. Just started at mandate removal. Engine runs so much better at low RPM but have to be careful with the throttle on hills. Any help would be greatly appreciated! Thank you so much What you describe is the classic, well known symptoms of a bad delete. There is a set of turbo derate issues that do exactly what you describe located in the ecm memory that persists after some completely clueless person flashed your truck, and likely never addressed. Here is some info on this at about a third into the post... http://rawze.com/forums/showthread.php?t...4#pid64964 User's Signature: ->: What I post is just my own thoughts and Opinions! --- I AM Full Of S__T!. | |||
