Single turbo with greddy profec b spec 2 settings

Hi I've recently upgraded to a larger fmic and a new boost controller I got my hands on a new greddy profec b spec 2 I'm currently running a t04b with external wastegate and don't know which settings to input into the controller to be able to drive it to get re mapped I was running 10psi on my old boost controller as one of the solenoids broke I've researched the forums and found these settings in the attached picture would these be suitable to drive gently on

Boost controller tuning takes a lot of time. Every car is different. You can copy someone else's settings as a starting point but there is no set setting for what you want. You just have to play with it until you get what you want. The manual for the controller is actually pretty useful and there a post on an evo forum that goes super in depth on how to use it.
