UTEC doesn't adjust the ignition and VTC maps which is a limiting factor.
There's a maxima guy that posted 275whp with less mods than me and no cams with the UTEC and TS flash. I'm adding the UR underdrive pulley, NWP spacers, removed the VIAS, will most likely get the SSIM since I'll be revving higher and am adding a pretty aggressive cam. Anyways I'll post the results when I'm done I don't know if I'd hit 300whp exactly but it's worth taking a shot at without diving into my pocket to get pistons rods etc. So we shall see
My current mods are the JWT clutch, Custom Headers, Custom Y-Pipe, 2.5 catless exhaust system, CAI, Spec V gears, Ported IM. With those mods I put down 250whp/268 tq. No tuning or anything done yet so I'll see if I can push it over 300! Woot. I'll definitely be close if I don't
I'm also going to be advancing the timing to 17* as well.

I'm also a little skeptical about 300whp without rods, pistons, and headwork to increase your compression to hit your mark. There's only a handful that has hit it N/A on my350z, and they had upgraded rods, pistons, and headwork.
I have similar goals in mind, but my component list is a little longer. Good luck!
