yep! 
*edit*
you should ask Jared at uprev how much could push the engine more. I asked for a really safe tune to be used on road course for long time (12.6 afr target), the regular tune is for 13.1/13.3 AFR that usually gives you more HP in the short term but tends to cause overheating problem if you beat the engine for 15/20 minutes without a break in the texas summer.
I don't know enough the Z engine to tell how many HP more you can get.. but I assume between 4 to 8 easily, tuning for power. if not more.

2HP from one dyno to another? if you don't have HFC probably you're going to get 10 more hp on the dyno where your car was tuned in the first place.
even putting both our engines on an engine dyno we could end up with a 5% difference just for were we are in the tolerance of the engine itself.
the dyno should be used for what it is.. a tuning tool, not a reference.
I have seen people posting "uncorrected dyno chart with very low smoothing"... well...
here we go.

BTW: Just a piece of friendly advice dont waste your money on N/A mods you cant use with a Turbo/SC application. You tell yourself that you will never get a kit and will be content with N/A power..but for most there is never enough power.

nothing to blame with who spend money on a TT setup, but I still have to see a TT setup on a 350z, not owned by a shop or where the money spent couldn't give you a 997 gt3 that is running in a reliable way around a track.
those "power mods" are to me ways to make the car lighter, that's it. I'm not chasing 300whp or 320whp, that wouldn't make any difference if you don't know how to handle 300hp around the corners. Unless your only driving ambitions are to bust a viper at a stop light.
mine are being in the fastest around a track, any track... that's it. this tune (if you check the A/F ratio) isn't for power, is for a "cool" running engine.
again, I don't want to say that driving around corners is better than flooring the pedal on a straight line... but IMHO a 350z is way more rewarding for the first job than for the second. for the second I'll just pick an american muscle, with a shitload of displacement and add the twins... or a supra.
but anyone has the right to has his own taste. somebody likes the taco, somebody the sausage.
I saw your car getting tuned at uprev but didn't stay for the final results. If i remember correctly you started out at about 256rwhp on the base line run. Sounds like they did a very good job on your car.

Ooohh, thanks bro. will be doing this after I install my test pipe and y-pipe. Is there a difference between uprev and protech to do the tune and dyno? A guy from here in the valley went to protech to tune his '03. he said he like it. but I don't know. Again thanks a lot guys.

I'm waiting for the 3.9FD and tomorrow I'll be able to ship the diff friction plates to wpc for the treatment.
maybe I'm going to have the differential rebuilt the week of march 16

they have a HPDE at TWS on sunday april 5th... 2 weeks of DD should be enough to break in the diff

Man, I'm sorry but that advice doesn't really work for me.

with 5200 for what I know you get a tuner kit, and you still miss all the bells and whistles to have a 350z "track ready" on par with a porsche.
when I'll see a 350z, not owned/sponsored by a shop or without 15 to 20k in mods to support the life of the turbo kit going often at hpde events without blowing engines every other time or without 3 cooldown lap for every fast lap... than we'll discuss.
If you're so sure, should be plenty of videos between youtube / streetfire / vimeo of turbo 350z running fast for 2 hours a day and going back on their own wheels, used as daily driver and than going to the track once in a while.
I don't care, absolutely, if a 350z TT, if a civic quadturbo or a viper smokes me at a light or on the dragstrip...
what concerns me is seeing people like mthreat here that smokes me around the corners with a less modified car because he's a way better driver.
putting 200hp more into the car doesn't makes me a better driver, maybe faster around a track, but not a better driver.
having a fast car around a track is only a money issue.
you can buy a radical or a zonda F, or an open wheel with shitload of wings and have an insanely fast car.
or you can invest in yourself and become better.
I'd rather invest those money in driving school or for a master.
p.s.
in your math of a porsche for 5200$ you still miss the Z to start with and all those mods that a turbo porsche has.
but....
feel free to prove me wrong, go to an hpde event on any track, smoke a lot of turbo porsches (is plenty in any hpde) , record it (a go pro camera is 100$ or so) and show us.
should be easy with your turbo kit, right?
*edit* sorry for bashing on you.
but lately this kind of discussion did become quite annoying, with plenty of TT track heroes that at the end are just
"e-drivers" and every damn time they have and excuse ready to skip events... and incredibly all the excuses are about the car not running properly... how is that possible if the TT setup is so "super"?

Honestly to run a turbo 350z around the track you're going to spend $30k + Ask people who do it. People that don't spend that money end up with broken cars, and end up paying the money rebuilding something and learning from their mistakes.




See sig if people want to see the numbers.
