previous owner didn't have a boost controller or boost gauge installed.
not even a bcc..
so why would he change the wastegate spring?

Thats normal if you have a DP and exhaust. The stock wastegate sucks and can't control boost all that well, especially once the exhaust is opened up. On cold nights I couldn't turn my boost down below 18psi.
