boost?
picked up a new '18 yesterday w/ 68RFE...noticed at hwy speeds 72-75mph & 1500-1700 rpm the factory screen shows virtually zero boost pressure...doesn't seem right is that typical?

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. |
