have a garret gt28r...car is running great...but one question
from around 3k to 6400 i hold a steady 4 psi...once i hit around 6500 i jump to 8psi and hold....the turbo is internally gated....
just lookin for a reason this is happening?

 

actuator always goes bad.

 

internal gates suck....full-race kit here i come....its been screwed up since the first dyno pull

boo internal gates
