With the exhaust brake off, the turbo slams open and shut (quickly oscillating between 90% and 10% shut), I don't want the VGT to close when EB is off.
With the exhaust brake on, it drops to 8-12% closed no more (I'd like to get a little more closure, VGT max closed is set to ~94).
I changed back to factory map positions to see if it's a map issue or something else going on, and EB on it would go to about 90%, but off it would do the same oscillating thing. Has me completely stumped.
