Absolutely. When I did the first dyno on my 10 with a PCIII and TRE I expected it would be higher than 150 because that is what it should be stock. I was surprised it only made 149hp and 74 torque. So now when I hear someone saying "I got 180hp with pipes and a PCIII." I say :bs:I think the article said a lot in regards to what the consumer wants, I looked at factory pro dynos when I had my shop in Jupiter and it really was the way to go, but customers in general dont want to see low numbers , most of the time they just want a dyno sheet and have bragging rights.
There is a strange mentality with the sportbike population in general , its very rare you will see a Muzzy pipe on a Gixxer ,although Muzzy do their research , and the same for Yoshi on Kawasakis, you see a little more of that , but they have been branded because of their racing associations, even if the pipes make better power .
