i took out a TT boosting at 9psi with my n/a the other day off a red light. i heard a lotta excuses, but i still hugged my semi-reliable n/a that night. of course im still going tt once my z stops acting gay now, but hey...many complaints about n/a zs feeling slow are usually about non modded or not taken care of zs. i felt a lot different about my n/a after my mods from stock.
