no, this means your trucks doing what its supposed to be doing; protecting the turbo from overspeeding.Running JP on stage 1s and stock turbo.
With the redline disconnected, I can spin the tires on a pedal mash resulting in lots of black smoke and a SES light. The code is the standard wastegate controller malfunction. My gauge comes very close to 30 PSI
When i connect the red line, life is much slower. Mashing the pedal does not cause boost to raise as quick and there is no spinning of tires to be found. PSI maxes at just over 20 with sustained WOT.
Does this indicate a need for wastegate adjustment? Any thoughts on how many rotations are needed?
If you want more boost, get a chip. A chip wont blow your turbo or overspeed it; messing with the wastegate will.
