This is starting to get a little of track and it seems I the real people on here have found me by PM. The same belief shown here are the inadeqacies that at the very start I said we do not suffer from, YES we do get exactly the same results whenever we look at other HD's and believe that the entire industry suffer from the same limitations. We have done numerous back to back tests with bike dynos in our city and have found them to be within 2-5% of each other as you would expect.
I am beginning to wonder if anyone here even looks at the maps supplied by Screaming Eagles, because if you did you would realise how stupid they assume we all are, I have seen the problems and have been able to successfully deal with them. Once you have a small idea about VE you may find it.
To those who mentioned the inadequacies of an air cooled V twin, go straight to the naughty corner because these problems are all your fault.
Regards- Anthony

It is my understanding that Iron are 883's, and if that is true that would have been stock 1200cc evo level power years back.

Great looking run... I'd like to see the tune file as well... have you guys started enabling the PE table to get these numbers?

Our 1200's with intake, exhaust, and tune are only averaging 75hp/75lbs. It's beyond me how a dyno can show 85/88 with slip-ons and an SE air-cleaner. That must be the best tuned 48 in the world.
