How about trying some sort of octane booster to help with the pinging issues? Do you buy gas from the same place all the time?

Hey, guys, been working solid lately. On Vacation, now.

Now about HP numbers:
Kind of stings a bit, Uprev had ziltch for me, so I am going to Houston this next week and placing the Z on a Dyno. Let 'er rip. Hopefully have some cold hard facts to show. Place is called Carboy on Westheimer Drive in Houston.
Going in with stock exhaust system, carbs and headers. I don't have the fancy stuff RCZ has. But I do have a custom tune which seems to me very impressive. I was told the SC is ok with the stock 2.5" exhaust I have, only if I don't like the sound.
The SC is running well right now. Changed out the Vortech fluid as recommended at 2500 miles. Next interval is 7500. It seems that the more miles I put on it, the "smoother" it is getting. The blower still rattles a bit at idle. The signature "whistle" is neglible at normal highway speeds. I can't hear it. I finally broke the tires loose with VDC/Traction control ON today doing a turn onto a nice straightway. Felt great. The 7 speed Auto is just so fast! Forget it in Manual, I'm too slow. The Z is still smooth when passing somebody. I love that about this car. Just a slight depress on the accelerator and in a heartbeat, I'm in front! So much power here, I don't have to step on it at all. Oh, yeah and in a 25 mph headwind! I gotta tell you the Z drives far better than other cars (ok, especially the cube). Stiffer steering, finer control in the curves and low center of gravity. Oh and gas mileage has improved, too. Getting an extra 4-5 miles to the gallon. Averaging 30 mpg driving 70, for a fair number. So, yeah I have a happy ending to this story right now. Hope everyone gets theirs!

So the latest stillen can tune is making 23 more whp on 8psi on a manual car than a GTM kit at 6 psi makes on an auto car?

Wow.

out of curiosity has anyone performed any compression tests or leak down tests at all on the motors after install and some hard driving? I know that these motors are already showing signs of oil consumption here and there (not as prevalent as the older VQ motors by any means), so I'm just curious if these motors are holding up to the task.

When comparing GTM and Stillen kits please note that there are differences in kit components and this provides a huge range of variables that can change overall performance numbers, even though they're both FI, it's still not comparing the same apple to the same apple.... with that said, BOTH companies have had reputations with " exaggerating " numbers on what they claim (I have seen this with my own eyes first hand with a few FI built cars I've closely worked on). So you cannot take their claims as ammunition to compare the two really either.

what really matters is how they drive real world. dyno graphs don't tell enough of a story on how the car drives.

For example: when I had my stillen SC 350Z, it would dyno low even though I would be running 100 octane, custom stage 4 and new maps etc. BUT the way the car drove was great, linear power output all the way through to the upper RPMs etc. Sure it wasn't 420 HP that any stock motor Z could pull with a decent TT kit on it, but I had power in daily driving where they didn't. I didn't have oil temp issues like some of them did. I didn't have to worry about leaking wastegates like the older Greddy kits, I could go on and on. Real world driving is what makes a kit really shine. I can illustrate where having more power doesn't mean that the same car is any faster, in fact it can be much slower, all things are relative. Take the last generation Mustang Shelby GT500 vs the normal C6 vette. The shelby has 100hp more. yet it's slower in the 1/4 mile, any road course, 0-60, etc. In nearly every test, it's not faster if anything it's equal. Yes, they are two different cars completely, but if you're only looking at numbers and dynos (which it seems this thread is really all based on), then there you have it lol

If you really care about power numbers and that's your main selling point, save, build the motor, and go crazy anything less is a total waste. if not, why argue back and forth about numbers on paper.

Another person with no problems on his s/c, people need to STOP protecting GTM so much. I mean it is clear, that the problems werent design flawed, apparently like the GTM pipe as some are saying, its the tune.

I dont know, I think both companies are great, but as a vendor and a sales guy in general, Stillen is doing the best they can. People keep knocking it, but like most have said, GTM isnt really out their producing numbers they claim. Their is no perfect kit yet, though Stillen seems to be coming out ahead on this one now that issues have been addressed.

Good to see Stillen posting again, I personally am glad to see you guys back throwing in the comments here and there.

Wow, really?
Because I have not been on both sides here at all? Geez, you are blinded by stupidity and assumptions. I am really tired of this BS that is spotted in both threads. I could careless who has a better unit or who 'wins or loses' in this imaginary game on the internet. I picked the company because of what I wanted, but when people go around spouting wrong information, it is the reason I use the icon for facepalm.

You might want to go look at my posts again, I am by far the most neutral in any of these threads even with the ownership of a GTM unit. I really do hope Stillen pulls this through, competition is better all around and only one option can create even more problems (companies get lazy, ignore customers, etc.).

You want to attack me go ahead, but be very careful before you make a reply and re-read your own post even and as it is filled with some wrong information. Also, as a vendor I respect what you bring to this community, but maybe you should take look into staying neutral or not replying on topics like this.

Here I will help you out:

I will keep calm here, but what did I say was wrong? That GTM DOESNT HAVE A PIPE that needs to be modified, or that STILLEN DOESNT have an issue with their tune?

I am sorry, maybe you should go back and read what is going on on the forums.

What stupidity and assuptions are you claiming that Chris is blinded by? He seems to be very neutral and as a vendor (and business man) it's in his vested interest to have good relationships with both companies. I've actually been surprised by some of his criticisms of Stillen because he didn't pull any punches. For you to bash Chris because he is now praising Stillen for adressing the issues that he previously complained about is unreasonable.

How mis-informed are you? How about this...Dont take my word, why dont you just call GTM and have a conversation with Sam. I think then you would quickly realize who's "ahead". You say you like both companies...go ahead, communicate with them and see first hand what they are like to deal with...

Having an issue where the casting company adds to much material and the time to goto market is delayed due to having to hone/extrude the pipe is WAY less of an issue than the pinging/cold/hotstart/drivability problems the Stillen kit has/had...I would take a delay of part over tuning disasters any day of the week.

I have never said anything bad about GTM, but you just admitted it right now. They do have an issue with the pipe, but are fixing it. Also so you know since I guess you havent read, GTM was having an issue with Hot start also, so I think the misinformed person is yourself.

Phimosis

Talking to a company's chief promoter is the easiest way to become biased. Looking at all of the data is the way to make the most accurate and unbiased assessment of the situation. This is what Chris is trying to do. Stating that he is misinformed is insulting.

If you want to call things like difficult hot starts a "tuning disaster", then then GTM has a tuning disaster as well. The tuning problems that I initially had with my car were not issues that could lead to engine damage or failure. Those issues were fixed long ago. My car has been running perfectly since September. GTM has had a problem getting their kit to market. Once they start getting more cars on the road like Stillen has, other problems - like GTM's hot start issue - are going to show up... Just like they did with Stillen. Then GTM will go back and fix those issues, just like Stillen did. GTM's mass deployment of the kit and the surfacing of problems still has not happened. They have two cars on the road (shumby and dreamer)? Stillen went through that process in June. Implying that GTM is "ahead" of Stillen is simply not accurate.

Stillen gets over the tune issue and the kit is perfect.
