I know barely anything about wastegates, but after searching for a 50mm one I noticed they come in 7psi and 14psi:

Which would best suit my application?
Also just came across this:

Now obviously I'm trying to save where ever possible, so is there much difference in buying a Turbosmart rep one over a gen one? (besides saving $400)
Thanks
