You should be able to get around 200 whp or so as long as its tuned right.
this is correct. psi isn't what will hurt it. 10psi from a small/med turbo isn't 10psi from a large turbo. 200whp is a good place w/ a good tune. i've been boosted on my y7 for almost 3 years and a majority of it's life it's been over 200whp. i put around 15k+ miles a year on my car and it's about to break 108k miles on it.

do it right, tune it right, maintain it right, and listen to it and you'll be ok.
