So to help clarify this somewhat. As you can see Jay's previous post up there the explaination for the high numbers on the sweep test are a calculation to more or less equate what would be seen on a comparable DJ dyno.......a calculation basically.
So I went back and took a look at the step tests that were done on my bike (also posted in this forum) and checked out the step test for 100% throttle and sure enough the readout shows a max "true HP" of 157 HP and 81 ft/lbs.
So, going back to Factory Pro's website and comparing against some known figures that they have up there (since their recorded "true HP" figures are fairly consistent across varying FP dynos) both my K5 and Fuzy's K6 still seem to turn pretty strong numbers compared to the samples below.
