Good work Eric must be a real blast to drive!

Eric, the other reason people will use 3rd gear is for speed limits. Most dynos default with a 200km/h speed limit, unless they have been upgraded. Same as sometimes the car having a 180km/h speed limit.

Also as long as they ran the na setup in 3rd gear as well, it would have been a more accurate comparison.

We normally dyno cars in 4th, unless gearing or electrice limits come into play. Really high powered stuff we will dyno in 5th to help with torque management on the dyno.

So good Eric, I'm hoping for another ride next time I see you, will be cool to make a back to back comparison video from my perspective!

I looked at my old dyno chart and it was also done in third. 
 
Thanks for the comments all. It is nuts to drive as it makes so much torque all the time!

Thanks to MCT and Rob K. for those explanations.
I thought 4th gear being closest to 1 to 1 and less likely for tyre slip on rollers.
Hadn't realized dynos can't stand the speeds.
And I can vouch for it being "Nuts" to ride in with instant vicious acceleration !  Is good.

My best guess is that you will end up with 220-222rwkw when you get it sorted.Will be interesting to see how close I am. Doesn't really matter that much when you have such a flat and monstrous torque curve.

I'm going to say 235RWKW when it gets some intercooling and 250RWKW when on E85 :)

Time for an update:

I made a few changes and took the car to a different dyno shop. The car came into the shop and made 190Kw on the first run. They then modified my fuel setup and put a new intake pipe on, fixed my MAF sensor mount and the result was 213.8Kw again - but this was partially due to a different dyno.

Peak torque was 521nm and more impressively 380nm at 2250rpm.
The car is much faster now, but still some improvements to be made.
 
I recently shipped an ecu to Gouky in the US who will be modifying my ECU. Changes are listed below:

-7200rpm rev limiter
-Leaner Tune - current tune is seeing 10.5 AFR at peak
-Torque limiting removed (explained below)
-Higher Speed Cut (Current is 250km/h)

Unfortunately the immobilizer has to stay. The torque limiting in the standard ecu is between idle and 3000ish RPM to stop torque steer, which is acheived via limiting the VVTI tables. With this removed the car should make a bit more power on the low end. 

On the top end, the VVTI is again limited up past 5800ish RPM as a "soft" limiter. with the 7200RPM limiter, the tables will be extended. This should see more power.
 
Speed cut is getting extended to 265km/h, which is the maximum allowable from the ECU. My current gear ratio's wouldn't let me go past this much further anyway. I expect 250km/h to be  achievable, considering I can do 200km/h in a 650m straight at Queensland raceway from a rolling start. 

Unsure on what peak will be, this is a very experimental tune so I will be fitting a wide band to monitor it whilst the car "learns" before taking it to the dyno again. If all is OK, I will run the ECU at Wakefield.
 
I also need a new set of rear tyres for obvious reasons... haha. 

SWEET!!  Nothing more to say...

Nice work Eric, can't wait to see end result. I remember how scary the V6 was - I bet the boosted 2GR is even more pants-sh!ttingly frightening
