The horsepower numbers seem pretty high (+110 wheel horsepower increase), but the torque figures are baffling. Are you really quoting a 219 torque increase at the wheels? And this is considered conservative on stock turbos?

It says flywheel on the top, but it is only 461hp and not 503hp as factory says. The factory is usually conservative so it is probably 530+
After tune they show 571 so if approx.. 530+ to start it is not much of an increase.
If they are showing WHP it is too much of an increase compared to most tunes I have seen.
I have a bad feeling on this one.

Our dyno is a hub dyno which requires the removal of the rear wheels and then bolting the dyno to the hub. This serves as a flywheel output. Our dyno does not have the capability of reading hp at the crank.

so you are saying this is WHP and TQ?
I think the 461 and 480 are close to what I have seen on many other dyno runs but to say you get 110hp and 220 more TQ is not believable
and you say it is conservative???

I am only showing you what our dyno says... I just asked a few of our customers if they would mind finding a dynojet to get a few runs in for us. Will keep everyone updated for sure.

Not trying to be a skeptic, but 571 wheel horsepower and 699 wheel torque on stock turbos with just a tune, catless downpipes, and exhaust?

You should not have a bad feeling. The baseline number after drivetrain loss based off your rated hp of 530 is very close on our 461 wheel number. We have tuned over 10 cars since the release of this tune and have had no issues.
Our dyno is a hub dyno which requires the removal of the rear wheels and then bolting the dyno to the hub. This serves as a flywheel output. Our dyno does not have the capability of reading hp at the crank.

What happened to this car build. It took a couple of months to post a dyno sheet and it looks like you ended up posting the dyno sheet from the car you did earlier because the dyno run is dated in May.
Did you maybe just post the wrong picture? I will give you the benefit of the doubt but I do have doubt.

May 5 dyno run? That does not correlate to the date this car was finished, not even close.
That's a huge number
Just because your dyno bolts to the wheel hub does not make it flywheel horsepower. Do you think drivetrain loss happens between the wheel hub, and the tire???? You probably change the calculations on your dyno to read flywheel horsepower when you post the performance run, then those number MIGHT start making sense. Dyno manipulation is so easy nowadays.

This is the latest dyno sheet I have from that car which was taken 2 months ago. His car is actually here now as well.
