I can keep the VGT on a 1:1 ratio on my truck to about 25 psi, after that exhaust pressure goes higher than boost pressure. At 36 psi of boost I'm about 55 psi of exhaust back pressure.

BTW I'll be swapping manifold and turbo in the near future for this and other reasons. I've got a 2nd gen manifold and a BW 464/83/.90 sitting on the shelf now.
Yeah that's how my 08 was too. I had a lack Max. i'm pretty sure it read that stuff and gave you a ratio
