Boost pressure is about 5 psi when unloaded on flat rd and about 5-10 psi when I’m loaded on flat rd and when going up a slight hill or something it hits about 20-25 psi loaded

That's too low, unless your driving it that way intentionally. Why don't you get your program checked out before you go any further?
