STILLEN 370Z Supercharger System - Announcement!!!

Nitex

Seriously? Did the Z shop in question send dynos or any diagnostic reports at all? If not then I understand to some degree. I guess it would come down to your word vs theirs in regards to performance. However if they have been sending any reports on the condition of the vehicle, then you all should know how his car is responding to your tune..

In all honesty, ive never believed in canned tunes. Seriously guys, to some extent our cars are all different. And each car DESERVES dyno time for a proper tune. IF you want the stillen kit DONOT get a damn canned tune yet if you can not afford R&D time. On that note, if your going FI plan on custom tuning. Not be cause stillens canned tune doesn't work. But because you should not be doing it ANY other way. If you want to be "carb legal" either leave your car stock, or wait till the front runners have been patient enough to work it out (not a cheap stab at you tom, i realize you have been through enough).

With that being said, i think at some point Stillen needs to throw the towel in on the canned tune idea if its just not working at their advertised numbers. Either lower the numbers or the price.

On a final note, for all you front runners. There is always the chance things will not go as planned. We were all crazy excited for this kit, and were all constantly asking when will it be released! Things didn't work out the way we hoped. Its time to move on, either pay the 10%, or go get your car tuned the way it deserves to be. There is no need to bash Stillen anymore. Either give them your business or don't. I realize this is easy to say from the sidelines, but I want to FI just as much as the next guy, and hope this gets resolved.

They were sent seven different dynos. One for every tune they sent.


When i have to smog in 4 years its very easy for me to revert back to stock cats for smog.

Im going to lose about 2 grand on the deal with the cost of install, restocking fee, and postage. Im guessing no one is interested in purchasing this supercharger from me? Its in great working condition according to stillen It comes with 7 different tunes at no cost

I think this is what Chris from wheels direct has been saying consistently. A simple custom tune would probably get the job done, but Stillen doesnt seem to be manning up on that, and the customer doesnt want to bend using carb certification as the excuse. The simple fact is he has hfc's so I dont understand how you would be carb certified with that? Tom I know your having the issues, but how can you say you want carb certification when you have the hfc's, just go get a tune man and be done with it.

This man makes sense...good points. A tune that has to be approved by one of the most stringent guidelines for smog testing is going to maim the car from the start.

Stillen did screw the pooch at first by releasing numbers based on a pulley that was producing more PSI. I honestly think this was not done on purpose since a few customers (including myself) were actually sent the "overboost" pulley at first. So I think they realized it either wasn't safe or it wasn't going to pass carb. Either way, it's not going to produce the same numbers.

Interesting thing is that I rarely and I mean rarely go past 8psi. Maybe because I don't bang the limiter or because there's a slight pressure drop from my headers. I would not be surprised if Stillen tested the pulley and saw 8psi all day like I do, but then when the kit started going out, they started getting more and more people breaching 8psi on the dyno so they pulled it back.

In my opinion, no one's going to hit advertised numbers because of this...less boost + carb constraints. However, if you ask me, I think you can get 430whp out of the lower boost pulley if you get custom tuned. 450whp with the higher boost pulley that you might as well get if you ARE getting custom tuned.

tomnavone, no offense, but anyone who thinks dynos are in any sort of way useful to solving a problem like this, has absolutely no idea about whats going on.

We all know any tuner with experience can tune this kit. What I'd love to see is Sam make a safe, CARB approvable tune with this kit that runs completely smooth. Now that would be something.


I think most people are hanging on to that warranty more than the CARB cert. 3rd party tune = no warranty and no carb.
