Good Morning,
Hmmmmm, I had a 2008 350z, with Twin Nismo induction, 5zigen exhaust.....and yet it still only produced the factory 313ps (309bhp).
Could you enlighten me on how you managed to get that increase you claim from stock? A 2003 350z produced 276bhp, so I am curious how with similar mods to mine yours creates 328 (and increase of 52 bhp!)
I only ask, so that I can go to the garage I had fit my parts and take legal action for not giving me the power increase that is so easily achieveable as you have proved.....
