This GIAC flash is running 1.1 boost on 91.
LOl I highly doubt it...

Our K24 software will typically see 1.2 bar of boost at the spike, and taper to a little over 1 bar towards redline. With our file for 1 bar wastegates, the spike will be right around 1.3 bar.

I also wonder if this dyno chart is corrected to reflect crank horsepower. Otherwise, with a 20% AWD drivetrain loss, you'd be up around 650 crank hp and lb.-ft with just an exhaust and tune on pump gas! Could be, I don't know!

The current GT2 RS makes 516 lb.-ft torque and 620 hp at the crank.

Those are some strong number for AWD dyno. Very strong. In fact, I don't know that we have seen any that strong around here before. My car dyno'd 525 on a dynojet in 2007 which with a 5% dyno difference would put them close, but it was also in RWD at the time.

I'd like to see a trap speed on this puppy.

Exactly..forget all this dyno number stuff. Lets see some trap speeds and 60-130 numbers. THAT will tell us how much power your making, not an adjustable dyno...With 500whp, you should trapping mid to high 120's easy...possibly very low 130's in this good weather....good luck and get back to us...

my GIAC tuned(done in 2007 with exhaust, and intake) GT2 trapped 127mph, could probably hit 130mph with a decent launch

Oh boy here we go again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This is why this site sucks, we again have guys debating the merits of the dyno and the numbers and the plausibility and the, and the and the.........................

The Dyno graph was to show the difference between two companies base tunes. That in itself is what causes tuners and customers issues!!!!

To get the all important dyno numbers certain companies have sold everyone something close to a risky tune just cause the odd person will dyno there car and to not have a poor showing infront of the internet dweebs cause that is a boat load of bad press!!!!!!! I say bad tune because it was made to give best figures under ideal conditions; but get some bad gas or what ever else and you might have a tune that takes away from the longevity of a motor. Not a catastrophic failure but a slow death....

My take on this. Yes GIAC does a great job tuning a car for a certain package, Near stock package, then there package a, b, c or whatever they have come up with. if you want to add a little here or there afterwards they are not really interested in doing custom one off stuff. But they have there packages dialed in to run very well and yet be very safe under all but the worst and most unlikely of circumstances.

Now if the original poster had some issues and wanted to tweek and further enhance what he already had I am sure FVD could have helped, hence why Ronda from FVD is saying, hey lets figure out what you had.

Seriously this is why you choose a tuner that you can work with and that will work with you, One that is able to meet your needs now and in the future if you are a person that likes to continually tinker.

Now I have never worked with FVD but I know most good tuners can give you very close to the same thing any other tuner could if you are willing to work with them. That means some data logging and maybe some dyno runs if you really need to see some numbers.

And back my original gripe, to all those saying those dyno numbers are not enough; that you need trap times and 60 to what ever times to get to the facts cause that will prove _______??????? Now I am going to be really crass here, if you are sensitive do not read more of this.... To you all I say "_uck OFF" the original post was not intended to instigate a never ending debate about the validity of the peek HP number!!!!!

OK now you can start posting about what an ignorant Dill Hole I am.

Didn't mean to ruin your day by bringing up the differences in dynos! That's a lot of anger!

Besides the angst, though, I think you make a good point that both of these are good companies that can give you good results, and it's not necessarily fair to compare tunes unless they had an opportunity to work with the specific car setup. And yes, of course, we all realize that dynos are variable and are mostly useful for tuning and comparing modifications on the same car.

You can not compare dyno runs from different dynos,, as you can not compare different variables on different days on the same dyno.
But you can get an idea in comparisons IF ALL the Details of each run are given.

Wow..someone is off his meds? (I'll resist calling you a dill hole here, just in case you don't have a sense of humor either)

Clearly you were referring to my post. The point of MY post was this:

Everyone was posting about how great the numbers were (not so much about the delta, which was the purpose of the thread).

I was merely pointing out to everyone else that thought THEIR numbers were LOW compared to the OP's posted dyno numbers, that they should wait until the OP can post some real world numbers, because dyno numbers mean squat for comparison, unless sanme dyn o, same day, blah blah blah...which is all that happens when one of these threads apppears. No one is questioning the delta between the tunes. I don't think this thread is a surprise to anyone here, regarding the results.

TT that was not directed right at you, just the general direction several of those posts were going to take another thread! Those threads turn out to be exhausting debates IMHO!

And you got spare Meds!!! Dude share!

No prob...I really hate these dyno threads and I'm always very conflicted to contribute to them. It seemed that I was the only one that referenced any trap speeds and 60-130 stuff (other than Dez), so I made the leap. It's all good.
...and if I had any extra "candy", I would be sleeping already

Dyno numbers and 60-130 times are two differing areas. One is the reflection of the vehicle potential output, however 60-130 reflect how well the driver can extract the output of the vehicle.
I like the dyno posting since it is two different tuners on the same dyno on the same vehicle. Offers insight on how each tuners are different in their interpretation of the software.
