That's GREAT!
I know the engine and transmission is identical to the G37... except for the (fortunately) optional steering system. I wonder of that requires special tuning in the engine control computer, or if it is separate.
To anybody trying this - read all the above posts, the Stillen system is a great piece of work. Remember to note the post about the belt, that won't be any different here since it's the same engine.
And don't forget sway bars - the perfect addition to the G37, oops, Q50.

the only thing different like i said is the intake tube.... going to be a monster kit hopefully all the electronics will work in line with the tune and not fly all over the damn place

I'd like to see that intake tube moved back a bit, so that the belt is visible and can be more easily checked along it's full length.
With a 6-rib belt, there is always going to be a breakage issue. Only fix is an 8-rib, and there isn't enough room between the engine and radiator for this.

That's perfect... in a G37, there is room for an 8-rib on the supercharger. But the other pullies couldn't be changed to 8-rib because then there wouldn't be enough room to get a wrench in there.
Infiniti must have moved the radiator very slightly forward to make a bit more room? Or maybe the hybrid engine placement required it to be moved a but forward? The hybrid would require the engine to move forward or the transmission to be moved back... so perhaps the radiator location changed too?
So if indeed the entire system is 8-rib, the kit is now bulletproof. As is exists for the G37, the immediate boost of the supercharger stretches and slips the belt and it inevitably breaks. Cheaper belts break quickly, better ones last a long time. And any decent OEM system goes with an 8-rib. So if Stillen has moved fully up to 8-rib, replacing all the pullies, it's now perfect.

My install goes down the 1st week of April. I will be using a Mustang dyno but I will get before and after pulls since I am only concerned about the gain vs reading high numbers.
Mods currently are only Fast Intentions Resonated HFC's and Meisterschaft full catback exhaust. I am curious to see how it does with the SC alone before I start adding headers and upgrade the impeller.

Your "pre tune" numbers will be depressing, I made only+43WHP( 342 WHP) ,,From my bolted dyno run with tune (299WHP).. After custom tune I was up 113 WHP!! 
412WHP is NICE!!
412WHP is NICE!!
I just left Stillen HQ on Friday and overheard some Q50 SC rumors
Btw I got to go for a ride in their Stillen SC 370z and OMG for a basic install/tune it was amazing!! I will have a 9psi pulley with a custom UPREV tune, no doubt there will be plenty of HP to really enjoy. That Z was wicked!!
Visiting Stillen opened my eyes to so much more. They really have a great team behind some amazing products. Can't wait to install everything and see the end results.

Few pics from my visit to Stillen this past weekend. This was an unforgettable experience, loved the tour and all the detailed information provided about their products.

Pulling up the first thing I spotted was their SC 370z that I watched on YouTube over 100 times lol. Beautiful Z!

Kyle Millen then said would you like to go for a ride
[*]I immediately grinned because I was extremely excited to finally experience the feel of the Supercharger.<a href="http://s1330.photobucket.com/user/diego13g37s/media/A7677B3C-DD63-44D9-B744-2A6899F6A6A5_zpsjzugxgua.jpg.html" target="_blank"><img src="http://i1330.photobucket.com/albums/w572/diego13g37s/A7677B3C-DD63-44D9-B744-2A6899F6A6A5_zpsjzugxgua.jpg" border="0" alt=" photo A7677B3C-DD63-44D9-B744-2A6899F6A6A5_zpsjzugxgua.jpg"/></a>
Soon after the amazing ride along we did a walk through in their 100,000 Sq ft facility and Kyle kindly showed us around explaining the history and background about the company.

Meeting the team and hearing about their products in detail made me really appreciate the kit I went with, this is going to amazing once it's complete.

I took a ton of pics but this is all for now
thanks again to Stillen for the wonderful hospitality and the full tour. Kyle took time out of his day to show us around and you can tell how passionate he is about all that Stillen has to offer.We even went over how awesome their new AP Racing Radi-Cal BBK is and I am very impressed with this entire kit. Just hearing Kyle explaining what makes these brakes so great is far better vs seeing them in person after I received them.

And for the finale, I'm just gonna leave this here

SPD,
can you be more specific. Im looking into doin the stillen SC as well early next year.
the upgraded injectors and MAFS, is this something stillen offers or something you have to purhcase outside of the kit and replace? Anything specific to purchase you can recommend?

You basically need any 1000cc fuel injectors from a reliable brand. In addition to this the MAF's from Uprev are a must. Some say you need a bigger fuel pump, but some are fine without it. The Stillen kit already comes with upgraded fuel pump so not sure why anyone would need a bigger one but it could be where some people are living. Anyways other then that just a nice custom tune and you are good to go!
PS. Depending which transmission you have I would recommend upgrading either the clutch or the valve body. I have the 7spd so I did the GTM valve body. Not sure how well that's going for me right now as my transmission is having issues with it, but I am told unless I want to spend thousands more on a tranny upgrade its the best idea that is somewhat affordable. Saying all of this, I have also been told that the tranny should be reliable even if its stock with 600hp.
