Message: [QUOTE="2012dually, post: 1280247, member: 23182"] Hi everyone! I am a new member but long time viewer and am thrilled to have a 6.7 tuning section and is why I joined! I recently ******d my 2012 and have been playing with mcc but am having a hard time with a few things. The first thing I would like to tackle is the desired boost and vgt tables. I am sure all of us would benefit greatly on understanding how the ecm goes through the tables. So off to tuning! How does the ecm decide on boost? As in which table is the limiting one, vane position or desired boost? Say i am commanding 10 psi of boost at low rpm but desired vane position is 30%. Would the ecm limit vane position to 30% even though say boost was only at 5 psi? I am really excited about this and hope we can all help eachother tune our trucks just the way we want! [/QUOTE]
