Ive got a '03 BA XR6T with little mods. Cat back exhaust, growler cold air intake, SCT flash tune @ 10PSI Recently I have noticed the turbo seems to be choking or losing boost at higher revs, I don't have any gauges so its hard for me to tell whats going on, I have traction control off obviously, but it seems that the power is being cut out somewhere along the line. When I de-tune to 8PSI the issue doesn't seem to be there. Any ideas? Cheers
