Stillen's tune actually is working very well on my 7AT. The only thing I would like to have now is a Transgo shift kit, which GTM advertises as having in stock for the 370Z on their web site. But, as it turns out the the kit will not work on our cars. When I have emailed and called to inquire about the kit as to when it will actually be available for our cars I get no response from GTM.
