You'll be fine on a topmount, I run 24psi in my 405 on a topmount, but I wouldn't recommend people go much above that, maybe 22. Everyone has their own opinions on boost.
This pump, dare I say, has eaten an engine... But then it had a TD04 with welded wastegate running 30psi+. Just too much that was and silly welding up wastegates, asking for it.
