Shane , I'd say its a very happy dyno. Correction factors in broad terms allow the dyno figures to be recalibrated to a std as to how various bodies "believe" is just. The dyno's have inbuilt if you like, a weather station that measures air temp, humidity and baro pressure. Based on these numbers corrections are made. That's it in broad terms. Also there are different dyno manufacturers out there and they arent all the same. 6% variation is not uncommon.
Prob 6 weeks ago now a mate of mine with his gixxer 05 1000 met up to prove a point together as he had an Yoshi can and PC3usb fitted and mapped at a dyno place in Sydney and achieved 169hp STD . He rode across town to where I normally go now and his bike pulled only 155hp std all within 3 hrs. My 2002 dead stock Busa pulled 155hp STD within 15 mins of his run.
A few weeks ago I had another one of my bikes on the same dyno and I saw another ZX10R dyno'd - dead std with 3000kms and pulled 143hpSTD and the guy then spent close on $2K with a Akro can only and PC3 and the bike pulled 147hp. Good value.... I dont know.
I have other hard data of people dyno ing same bike on 2 different dyno's same day and have seen 10 to 12hp variation.
Just use the dyno as a tool for tuning rather than talking shit as the numbers are meaningless if comparing. Just stick with the same dyno if doing mods , to see if you are going forward or backwards. <i>Edited by: Gazza414 at: 12/7/05 12:37
