I just recently purchased turbo xs exhaust and the guy told me that if im lucky i wont lose power or if im not i will lose power. He said on a normal 350z you would gain 10 whp. Is there anything i can do to receive that power? Or would i have to go and get a tune? Also does the nismo not gain as much power on air intakes and other stuff as well?

 

Please research so you won't be taken for a fool...

All mods can produce a gain with a tune, or you'll lose power simple as that...
