STILLEN 370Z Supercharger System - Announcement!!!

tomnavone

its locked u arent able to alter the tune or see the parameters of the tune. All they have asked of my shop after every tune fails is to send them the dyno. My shop has called stillen dozens of times to talk about my kit. Im not hiding anything and we are giving stillen everything that they have requested. Believe me i would rather be driving my car than talk about the stillen supercharger shortcomings. Luckily my shop rocks they havnt charged me to install the 7 different tunes or the 7 different dynos. Stillen claims they have the right tune after the previous one failed i have to drive a hour to my shop, have my shop install the tune and dyno which takes another hour, then i have to drive another hour home. Three hours of my time for each tune x seven tunes.

Do you think it has anything to do with hardware or is it strickly a tune issue?

I know you're pissed, but if it were me, I'd go back to the "driveable" tune and just sit on it until Stillen can come up with a fix or stops trying. It doesn't cost you anything, and if the hardware is good, I bet the tune problems will get fixed eventually. Even if they don't, you get an custom tune and you will end up about where you want to be since no one else is going CARB as far as I know. A lot also depends on how long you have to return it. I'd check with Stillen on that. Otherwise you are gonna be out a good bit more money and more time to start over.

I have reverted back to the r6 tune from the newest r7 tune. The r6 tune is somewhat drivable but once u give it gas it has major lag and once the boost comes on the torque and hp just falls off the table. I think GTM is or was going to apply for carb for their supercharger.

I haven't had an opportunity to drive mine with the r7 tune so I can't really comment on how it runs yet. Although, regardless of how it may run I am going with a custom tune in the next couple of weeks. I spoke with a very reputable tuner in the Montreal area regarding the ongoing issues and he will just overide the Stillen tune with his own.

Thanks what Im talking about, this is the smart thing to do. Thumbs up to you, for doing this the right way. I tried to do the box tune on my old turbo setup and it was never right. Custom tune, and magic the car ran real smooth. The charge pipe kept coming off haha, but that is neither here or there.

Custom tune and carbed legal sounds fantastic hahaha!

On carb cert: stillens current tunes aren't carb
certified. If they get one certified and you load it into rom, will Stillen give you the sticker, or do you have to buy the unit after they get approval, then send it to youbwoth only that one tune? If they will give you the sticker when they get one of their tunes approved, how is that different than running a custom tune for now, then running the carb approved tune once it's here? They should give you carb sticker if you revert your custom tune back, otherwise, they shouldnt be giving carb stickers to anyone who buys the kit before they get carb approval.

On the topic of warranty: is there a warranty policy in writing? I didn't receive one. If it's not in writing, there is no warranty. If there is a written policy, can someone point me to it? I keep seeing people debate whether to do a custom tune because of the warranty issue. If Stillen warranties their carb tune, that means everyone who has run tune r1-r7 are running non-approved tunes which would not be warranty qualified. If Stillen will warranty their non-carb tunes, people
like tomnavone that are running non-stock items like
HFC's that could be causing poor performance with the canned tune, could get Stillen to custom tune their cars, get it work work right and still have the warranty.

Just a thought, but I need more info on the true status of implied vs written warranty.

weiboy718

Their warranty is for the hardware, not the car or engine. There is no warranty available till they get it carb approved.

shumby

wel then go get someone that knows how to tune your car to do it. I think you know who you should call

As far as I am concerned, the statements that Tom quoted were all lip-service (or typed, but you know what I mean). Those who have purchased the kit should have something in writing that details the warranty.

Well here it is...45min with a custom tuner and it was done. This was done on a Mustang dyno so the numbers will be lower than usual. Unfortunately i don't have a pre-kit dyno to compare. Since getting the tune today, the car has developed what seems to be a tip-in knock; so i will be working with my dealership/stillen to handle that. Even with the knock, the car accelerates great. Anyways, here's the numbers, i'll let you experts pick it apart:
