It did a baseline of 377whp 315ft lbs
So far I have about 2,500 miles on it and have driven to ATL and back which is about 2 1/2hrs away, and I haven't had any problems out of it.

-1000 to Sam. i don't like work with a unresponsive person.
i had a problem with pop off and bad tune.
never had support by gtm,
before solve my problems with sc installed dyno was:
the last peak is a dissipated power. @5000 rpm i had 40cv less before installation.
the only answer by Sam:
"I'm a little confused, your labled sc dyno chart reads higher then the before, so how can you say it is worse can you please explain ?
Sam"
COMPLIMENTS!!!!!!
with pop off ok, air filter changed, and the help of best tuner near my country:
(WITH 100mm PULLEY)
and here video:

Paolo,
First of all, I'm glad your car is back on track and working to your liking.
As for the "lack of support", we are only as good as the information we receive from you. You never mentioned to us that your bypass valve was staying open. This is very important information.
We received a phone call from the gentleman who took over your project. Good guy. It looks like he knows what he's doing. Here's what he stated: the bypass valve was staying open and causing a substantial loss of boost. He said that he shimmed the valve to get it to stay closed longer, but now there's a fluttering issue. He also noted that when he had the valve off, there was some scoring on the bypass valve piston which indicated to us that there may have been some debris that entered the valve and possibly caused it to stick open or not operate freely as it should. We advised him to take the valve apart, clean the piston and check for free operation of the valve. We also explained that this valve replaced the original Bosch valve we were using and that the new valve is adjustable. We told him to remove the shims and use the valve's adjustment to balance the boost holding capacity of the valve and fluttering.
As for the "bad tune", a tune cannot compensate for poor mechanical operating condition of a vehicle...period.

i'm not mechanical or tuner...
when i sent you the first dyno i sent also a log with cipher and i asked you what i had to look, i told you the car some time doesn't turn on, ect ect, but i never received help/answer (as usual).
i know the tune for email cannot be perfect and our gasoline is different, but base tune gtm for sc was veeeery bad. maybe is better for your credit avoid to send maps for email.
i asked you upgrade from osiris standard to osiris tuner = 454$ with GTM and 200$ with uprev...
so i said "hello" to you and i ask in Italy, i found Okan (tuner call you) and he solves my problem.
now the car runs from hell and made great numbers with 100mm pulley.
despite all, the kit is really well done and i'm very very happy too... finally.
i hope to work better next time with GTM for next project.
(if someone ask why i looking in usa for z parts... cause in italy is more expensive and we haven't absolutely the same choice... in this sense you are lucky!!!)
(sorry for my english)

Same thing here in Finland! Here's no parts at all 
I have ordered everything from U.S
I asked and searched but didn't find a tuner here who would operate with Uprev
It looks like I have to stick with emailed tune after ordering.

I haven't ordered it yet! But I'm strugling if I even order it because there's no tuners here (who are willing to operate with uprev) I wasn't clear enough, my english isn't that good neither.

I read on *******.com that GTM finished their Stage 2 Kits for 350z VQ35HR. I was reading the 370z's Stage 2 Kit was completed and began shipping a couple weeks ago. The Stage 2 Kit looks very promising for the 370z. Also read your working on upgrade kits for people who already have the Stage 1 looking to go Stage 2 in the future for the 370z.
Sam can you chime in on the future of the Supercharger kit for people who own a VQ35HR. Confirm these rumors? What can we expect, what is in the works?
Just trying to inform my fellow HR's, since this thread seems pretty dead.
