I did that this morning as well as disabling the EGR to see if that would change anything, and my VGTDC is still WOT (7.001%) cruising down the highway. But that isn't my concern, the truck runs really nice there and EGT's are cool.600-650 on level ground. It's when it just feels like running at 65-75% closed is. EBP is way up there. It does this when it wants. Almost like every now and then it just likes ***king with me. Nothing like having a truck with a sense of humor eh? LOL
New EBP and tube already. EBP and MAP are the same KOEO (13.4psi absolute). So all the sensors check out.
