IX w/ DynoFlash
That is a ridiculous amount of torque for such a basic amount of bolt ons... I also have the same mods plus an LICP and was tuned by Al on The Shop's dyno and only made 305Tq. About 10 less Hp then you too. That would pretty much guarantee well over 400 Tq on a Dynojet with just a stage one and O2 housing. Does anyone else think thats crazy? I've definitely got torque envy.

What boost were you tuned at?

No but seriously, somethings up with your ride. There was a IX there tuned by him with a stock exhaust that made more than 310 wtq.

Vishnuite? What does this have to do with Vishnu?
How about spoken like someone who's been setting up and using a Dyno Dynamics for almost 3 years?
Anyone who has ever run a DD and is familiar with an Evo can see the discrepancies in that graph.
BTW, I already know The Shop's correction is 1.15- pretty much because I saw it in that video you had up here when you CTRL + X'd it up while the camera was pointed at the screen. I have lots of hours staring at that exact same DOS based interface.
You should fix the way you get the tach signal too, because your torque is getting dramatically inflated by the fact you're scaled wrong or your signal pickup is off. Huge torque at 2800rpm and signoff at 6800? That dyno is showing almost 1000rpm lower than it should be. No wonder the torque reads so damn high! The power isn't as screwed up as the torque since the dyno measures work (HP) and plugs torque in as a function of the RPM scale.
Turn those corrections off and scale the graph correctly, and that car will make 287whp and I'd guess about 310Tq.
You know what, though? It doesn't matter, since that's you have it set up all the time and the Dyno is only a tuning tool. Its not like you're hiding the fact there is a correction; you already admitted it. Maybe I'll run at 1.15 with the electronic tach signal pickup like that for a fun comparo sometime.
it doesn't matter what the correction factor is because if all 3 of us got tuned on the same dyno by the same tuner with basically all the same mods... and one of us is making rediculous amounts of tourque??? that's the question we are asking, not who's dyno is better...
TQ on the IX is generally related to boost levels
All things being equal - cars with low TQ generally may have a bad tank of gas at the time of tuning and we may hav run the boost lower than another car to avoid knock counts and pulling of timing
We also try and tune out knock with timing - MIVEC and a/f corrections - however often there are cars that we have to run lower boost on to keep them safe and smooth
The difference between a peak boost of 20 compared to 24 psi can make a huge impact on peak tq
Tuning is about responding to how a car reacts to adjustments and knowing how far to push the envelope with regard to saftey and engine reliability. Gas quality is a variable which fluxuates greatly from day to day and a reason why street pump gas cars need to be set up in a conservative manner.
Finally, our dyno uses no temp correction (I dont like to use one). Many cars dynoed on a cold day will make 10 or so more TQ and whp than cars which are done on a day with hotter temps in our dyno bay.

And I agree with you that it really doesn't matter if you're comparing with the same dyno. Because you all 3 can definitely compare your charts to each other.
I'm not hating on Dynoflash. Its just really hard for me to see a graph and understand what I'm looking at with it setup so differently than standard settings, that's all.

These days generally the dyno is set at 1.10 correction as I have found after much experimentation that is the correction which most closely aproxiomates the results obtained on other local dynos.
As you point out its all irrelevant as the dyno is a tuning tool and I am not that interested in what the peak numbers are. Rather - the shape of the curve and repeatability are the keys to a great dyno.
I believe Noize was explaining the reason the torque was so high is because this particular dyno has been manipulated back and forth. Bottomline, this dyno doesn't read like a true Dyno Dynamics and is actually closer to a dynojet IMO. And judging by the recent graphs I've been seeing from this place, it seems like this dyno's settings and correction factors are constantly changing. I've seen stg. 1 IX's put down close to 350whp on pump, and then others with similar mods but down about 315whp.

We do use the temp correction, but sometimes to our detriment. I agree that a cold day will inflate output a bit, which can suck if you try to compare one day to another.
IXs have sledgehammer torque when tuned compared to VIIIs. It makes me miss my VIII less and less every day.
