That sentence really bothers me as this can't be further from the truth. No canned tune can be 100% safe, especially when force inducting a car that is normally aspirated from the factory. Even a custom tune for the car will never be 100% safe.

No offense, but any vendor who will say that their tune is 100% safe is basically lying.

Obviously it's only safe as any tune can be safe... Even the OEM tune can cause problems.

I don't think it's worth to have a full discussion on this, but when done with safety in mind, done correctly (correct install and within the limits of what the engine components can handle) and you look at how you can compensate for items that could damage the engine, a supercharger setup like this is a pretty safe bet.

You might not want to take my word for it and I'm not saying you should, feel free to disagree.
But maybe my statements have some more credibility if I told you that I have worked at Jaguar (uk), where my team was responsible for the calibration of the V8 engines, this included the NA and SC engines. So I've spend my fair share tuning engines for performance, safety, mpg and emission. And I know what it takes to break an engine and how to ensure they are reliable...

My reply, which I thought was clear, was in regard to Kyle's statement that the Stillen tune was 100% safe. It seems you have some experience in tuning, certainly much more than I as I profess to have none, and you must agree that Kyle's statement is not factual?

We are talking about a CARB legal tune here also.
This is not top PSI running unknown parts, many people will be running stock cats or HFC to keep legal which can easily be calculated for, same with exhaust. This tune will be very simple, designed for someone to DIY install this kit and plug-n-play a tune. It will not be the top performance tune, but it will what can legally be done for CARB approval.

How long is this Intro pricing going to last? I return from deployment on the 2nd of April, and i have no way of buying until then. If this sale is gone in a week, im going to flip out.

You have it a little backwards actually. Most canned tunes are extremely conservative while custom tunes are running closer to the edge and are more sensitive to temperature and altitude.

But yes, nothing is 100% safe when it comes to modding.

i think your going to flip out...i would contact and just put down the deposit...and just make sure that you are on the list

That is probably why Stillen hasn't released info/dyno's on the two other kits yet. They are probably testing them to get a "safe" tune as we speak. I don't know much about tuning, but I wouldn't go as far to say that it won't be safe. It comes with an engine warranty as long as its not custom tuned...We know the s/c (CARB legal) can handle heavy stress on the track for an afternoon or however long they tested it for. I want to know what its going to be like for everyday driving as my Z is my daily driver. I'm sure it will be ok, as Stillen has been working on this kit for a year(as they've said), and they will make sure its a reliable product. That said, we just have to have a bit more patience and see what comes.

Also, they said that they will have magazines do reviews on the kit. So there will be an unbiased analysis.

Not true at all. Custom tunes, if done properly, are designed for the actual car and the actual conditions it is being run under. No canned tune, no matter how conservative, can come close to the safety factor of a solid custom tune. I don't know what tuners you use, but any that would put you on the ragged edge with a custom tune without being asked to do so is no tuner I want to have touch my car.

Does the Stillen SC require us to remove and not re-install the cross-bracing?

The supercharger fits under the FSTB, according to Stillen.

If anyone actually thought that I meant you can install the supercharger and drive 100% safely for 500,000 miles I apologize. I guess I was too generic. Obviously there are other factors that come in to play that are out of our hands as well as out of the hands of the owner of the car.

If the supercharger is installed correctly and you always use 91 (or higher) octane fuel. And you do regular oil changes and maintenance. Then you will have a reliable vehicle. We have numerous customers with hundreds of thousands of miles on our previous supercharger systems who have never had any issues.

That is correct- The supercharger does fit under the front strut tower brace.

Ive had canned tunes on my last 2 turbo cars with various mods and never had any problems with the engine or anything other than a blown diverter valve which when it blows you buy an aftermarket one thats meant to hold the boost anyway.

I am a firm promoter of custom tuning. Each car is different and has its own set of quirks, therefore it should be tuned specifically for those differences. That is only true to a certain extent though because shelf-tunes (non-custom) have been getting better and better over time due to the adjustability of the software and increased consistency from one car to the next. You may be able to squeeze a few more horses out of the tune by going custom, but that will almost surely also mean that you are pushing the tune a bit more and making it less safe.

Stillen (or any tuner for that matter) can't have cars blowing up everywhere so I'm sure they are leaving a good margin of safety that they feel comfortable with. Specially with the tunes that are warrantied. People should not be worried about the safety of their engine unless they are modifying the kit or the tune or have a setup that is not suitable to running the SC.

Although I could very easily custom tune the car after I get the kit from Stillen, I am not going to do it. I think their tune is going to come at least 95% of the way there and that is acceptable to me when considering how much of a safety net I need in this climate.
