I called Stillen up as well as GTM but first I called Stillen and spoke to a guy named Kenny more than once.Now Im sure everyone is aware that when you call Stillen they take down your info.The first time I called Stillen I explained to the Kenny that I had a 03 vortech superchared 350z that has the same blower that there kit has. I ask them if they would sell me all the other parts besides the blower it self because I was planning on getting a 370z. I did not have one at the time I do now. I also explained to him that I was not satisfied with the numbers that there kit is putting out on other customers cars and I would like to make more power 430-450 range,and if I did get there kit I would run a custom tune. On my 03 Vortech with 10 pounds of boost 350z I made 415whp 350tq with the same supercharger. I have kept track of both the Stillen Supercharger as well as GTM.He advised me not to buy a full kit and that he doesnt think that the Supercharger will fit we shall see once I get weiboy718 kit in my hand.

Now back to my concern about there kit Stillen was trying to sell me there full kit I have seen enough info on there tunes to know to stay away from it.I got fed all the info that there kit will be going carb as soon ,Kenny told me next week this was a month ago. After that they would then be going balls to the wall and coming out with different stages. I then explained to him again that I have no interest in using any of there tunes and would be going custom and would like a pulley that runs more boost. I also told him then that it was between them and GTM I then got the GTM bashing talk. He then said if I wanted to run a custom pulley they could make me one because they make them in house.

Now On to GTM when I called GTM I spoke with SAM and explained to him that I was looking at there kit and Stillen kit SAM did not once start bashing Stillen.Sam then asked me how much power I am looking for and I told him he told me to get his turbo kit.At the time I was not thinking turbo but more so Supercharger Stillen or GTM supercharger but stage 2.This is because of the install my self and 2 of my friends will be doing the install.Sam told me and was nice enough to send me the instructions in a e-mail of installing the turbo kit with out dropping the motor. At this time I really started thinking turbo kit.

Ah this is long sorry people lol.

Ok now back to Stillen I called them there other day and spoke to Kenny yet again about selling me a custom pulley. Now all of a sudden he wont sell me one and begins to say that when I get my get from weiboy718 Im going to have parts missing and will be calling him back for some parts.He then wanted to tell me there side of the story I then told him I dont care.I never once said weiboy 718 name to him I just said Im getting the kit from a un happy customer thats all.

Sorry about the long post there it is if I missed typed something sorry.There is more to it that I can add but in the end my experience so far has been like pulling my hair out.
