Your butt dyno will approve, the dyno at your local shop will show gains, your wallet will be fatter due to the increase in fuel economy, and your engine will be more responsive all around.
The 20 pages of feedback from Z owners here in this thread back all of these claims.

I tend to agree with you or I would not have just purchased a NST under-drive set (just arrived today BTW).
Very good quality parts too. Now if I can just get someone to install the things. I'd do it, but don't have a pulley puller and the last time I tried to do the job on my former Maxima SE...well...I ended up taking it to the shop anyway (could NOT get the bolt off...even with an impact wrench).
