I'm running 18psi in mine and I rarely see EGTs go over 500°C. My probe is 50mm after the turbo.

ZD's are definitely no torque monster but in my opinion do a good job of moving a big car. There are a few guys getting really good torque numbers but as said its not cheap.

See this link for a good visual representation of boost/EGT relationship.
