Not sure what all is taken into account but I know for sure that actual displacement of the engine and compression ratio plays a large part in finding the correct psi. You really need to figure out what the safest psi to run, not the max. Im not a turbo guy but I have learned this much just from hanging around my turbo buddies. Im sure others can be more elaborate.

All that I know is that when the Greddy guys set up the TT kit for the 350, they have it set at 6 pounds of boost and got a 90 HP bump through stock cats.
