I don't have any boost pressure at that speed either. The KW shows 20psi boost at that speed.

my '03 would run 8-12 at hwy speeds and hit 20 climbing grades
this '18 barely hits 10 with my foot in it uphill and runs along at hwy speeds with no visual boost unless, shows a little accelerating from a stop

You have an VGT actuator problem. Probably stuck. |
