My journey with GTM SC stage 1 Install so far
 

Hi Guys,

I paid for a GTM stage 1 SC kit for a 370Z on the 21st of January 2011 - from Sam.
After too many calls, mails and threats to cancel the order, I finally recieved the kit on the 29th of March 2011. I was promised a three week lead time in January. I must say that the kit is very well packaged and has a detail packaging list.

In spite of following the steps in the manual - starting on the 30th of March with the ECU details, my kit still sits in the shed as I have no ROM files to load into the ECU. I have called several times, emailed etc. - no luck. Every time it is the same story - I will receive it within a couple of hours etc.

Can the guys who have completed their installs please advise me. Should I send the kit back to GTM, or do you think I will eventually have everything I need to actually do the install?

I am based in South Africa - are the rest of you getting the same level of service from Sam?

Thanks for the build Modme, looks great. There seems to be no solid database yet for either so hoping a Z/G database here will help centralize things.

-Kit used: GTM Stage 2 Twin Turbo
-Current HP/Torque: 540RWHP/460RWTQ @10.5psi
-Miles since kit installed: 6000

They should be able to load the basic tune via internet. they can send you the program that way too. If your missing something in the kit they have to give you what your missing.

Hi Guys,

Just finished the install

2009 370Z Stage 1 GTM SC
at 6000ft above sealevel - getting 6 psi with smaller pulley from Sam
(this pulley would give 8.5 psi theoretically at sea level)
Using free flow system with test pipe.

LOVE the conversion - congrats to Sam and GTM for a great kit.

Do you have a dyno of your numbers, want to update the list of builds. Also, do you have a manual or automatic?

Any other finished builds?

Have added about 5-6 more people today, if anyone knows more builds that I am missing please let me know. Remember to include these key items to help others:

-Year

-Current PSI
-Miles since kit installed
-Other upgrades (clutch/flywheel/engine/etc.), also include miles when these upgrades were completed with done after original FI install
