you are a welcome member ZBOYD on here
with some good knowledge to bring to the table.
RR days forum threads are always like this
And will be again for the next one.
I'm sure if we took a stock ED30 , it would run 255 at Awesome and Prosport and 235 at JKM. (on same fuels)
Which is 'absolutely' correct I dunno , but in terms of reproducibility they are all comparable if you stay on 1 dyno 
If you added a remap to that ED30 you would still see a +XXbhp difference no matter which dyno.
And thats the key here.
What is clear though is that the numbers across dynos ARENT comparable.
I also believe that given the data on here , I could 'work out' what my car would produce at JKM (317 - 20 = 297bhp)
Of course this could all be sh*t and its just that us Northeners got the 'better' Golf GTI's 
only 237 bhp Phil
, you running 95

Thanks,

I don't confess to be an expert but have my own experiences over the years to cast upon.
I'd actually expect it to run lower figures at Awesome than Prosport. Based on the historical data I have so far anyway.
It would not surprise me to see it drop 10-15hp at Awesome next weekend.
Common sense would indeed dictate they do what they are supposed to do, but I didn't get a dyno report with my new car to tell me what it was doing the day it was bolted together. I'm pretty sure no-one else did either.
There may well be nothing in it at all, but without supporting evidence from the manufacturer other than their marketing spiel its not unfeasible that the cars leave the manufacturers with an under or even over estimated figure either.
I did some logging yesterday in VAGCOM, and based on the air mass readings it's pulling around 315-320 hp give or take. Which is probably 10-15hp under what Prosport read it on their road.
The last time it ran at Prosport without the new modifications it ran lower. At Awesome it ran lower still, its back at Awesome on Saturday, I expect it to run lower figures than Prosport possibly in the low to mid 320's with the new modifications.
I do not rely so much on the accuracy of the numbers but the fact I can see a change, based on the last time it was run and compare it to other cars of a similar ilk I find to be genuinely useful. I also never brag about my numbers or get to hung up on them, because at the end of the day they don't really tell the whole picture, especially 'peak' figures that so many people latch onto as being 'all' important.
It's never a standardised situation any of us run are our cars under, so at the end of the day its mainly a bit of fun and if it gives you a general idea of whereabouts you are in the grand scheme of things then that is all that really matters.
We do have colder air up north.

and the beer doesn't taste funny.
