Well my G37 specifically has had a ECU dump that was sent to Up-Rev back in may. I spoke with Rich@Uprev on AIM about a hour ago and he has told me the G37 is good to go.
SAM@GTM is able to tune the way he does because he works very closely with up-rev to develop this tune, and make it applicable with the turbo kits.
Anyways, i do know that the 350z platform has just about 20 different "variations" in the same ECU, and they have them all, and "patched" them all. so the 350z is basically fully supported.

This is what I ment for the different ECU platforms and numbers. You have to figure out all of them before you release it to the public or you're going to have downtime on some cars being tuned. Not saying you can't use the same map for every ECU like Cobb did, you can do it, but it won't be 100% correct, this is my point, it wont run right.

Edit: ok i asked. he says cam phasing only applies to intake and exhaust cams that have phasing. VVEL is a totally different beast, so it wont apply to us 3.7 folks.
Cam phasing only applies to the G35, Titan, and 350z. "Cam phasing" isnt the same as "vtec" though.

Will this be important in the tune? I hope they can get as much as they can out of my car.

Just don't worry man, give them your car, go outside sit down relax, come back later and it'll be faster 
UpRev was on here trying to tell everybody what sup, but people were too newbie at that time to understand, and plus Cobb AP was already out, and all the vendors was pushing it so when UpRev smashes the product that the vendor is pushing and whom has to pay monthly fees for to be able to push it, it doesn't work out to great if you get my drift.

You want a real tune? Get a piggyback or better yet, a full standalone.
Can the AP/Osiris be used to potentially gain performance? Yes. Is it as good as a full standalone? not even close.
On the flip side, if you're NA and you want a tune, well... why? This isn't a wrx/evo/sti/gtr/domestic.
The car comes pretty damn well tuned from the factory. This isn't like the older VQ where there was plenty of room for gains. The only REAL reason to get a tune is if you have test pipes.

Full standalone is out of my price range.
I was under the impression that if i tuned the car stock, there would be very minimal gains. However, when the car is modded, the tune becomes slightly more beneficial. This was the reason why i decided to do intake, hfc, exhaust, and now id like to fine-tune the adjustments so the car can make the best use of these parts.
i understand that the gains will not be astounding, it may not even be more than 10-12hp.. but its just like any other mod that we do. This guy (Semtex) got a gain of 6hp with it http://www.the370z.com/tuning/10654-...semtexs-z.html
But Mike, i do have a question for you. This tune is supposed to be able to raise the redline by 500rpm, making it right around 8k. is there any harm in doing this? the cutoff from stock is like around 7800.

Long term repercussions are unknown, as the VQ37 is relatively new. From a mathethematical standpoint, the pistons speeds would be at just around 4500ft/min. Stock is closer to 4200. Piston walls shouldn't be overly stressed, and FI applications (so far) have been fairly successful. Long term effects on the rods and crank? Again, FI has been successful. (Problem here is, the guys with big HP don't seem to drive very hard, so we have to play the waiting game)
I'm friends with a maniac driver that revs his [NA engine] to 8000 regularly, and he's yet to see any engine issues. (He does religiously change fluids in his car, and uses top of the line stuff, makes sure oil is always topped off, etc.)
My reasoning behind recommending against a reflash on a VQ37 is that the engine is tuned near perfect from the factory. Cam timings (or what is effectively analogous to them) is literally ideal from the factory. AF is slightly on the conservative side, but anything more aggressive wouldn't work in all weather conditions (and even the factory ECU is constantly changing this based on readings). The factory intake isn't a restriction at all. Hell, even the throttle body isn't 100% open. It doesn't need to be.
The exhaust could modified, but with the cat in place, your biggest restriction is still there. A test pipe is the only TRUE gain on this car. Once a test pipe is there, the other supporting mods start to have a bigger effect, and so will a tune.
As far as the revs go, if VVEL could be tuned, then higher RPM would have quite a benefit for output, but right now, its just mostly extra revplay. The VQ37 has quite a meaty powerband up top.
You could always have a cutout placed in front of your cat that opens only at WOT...
