As far as losing and hp, well that I can't comment on. Maybe someone did, but when comparing it to using no lid and the seat off while doing the dyno test? I just don't see it losing anything with that lid vs stock airbox lid. Not like it is some open class street bike with ram air and factory box tuned for it.
I was at Ferracci's holiday party last week and discussed many things with them about this. One thing is it will be tuned as it will be ridden. Same tires, same air pressure, same way it will be ridden. I don't care about peak numbers, only a safe tune with the most area under the curve.
To me it would be pretty stupid to dyno with the seat off, anyone who does that is just trying to get a bragging rights sheet.
There is a good reason for dynoing with dyno tires though, the knobbies slip in the rollers and you do not get the correct load to do an accurate tune and correct A/F readings due to slippage, that and your leaving power and TQ on the table as well as it is inconsistent as hell. It's hard enough to get the quad secured and get no slippage with a set of flat track/dyno tires, to do it with knobbies is just not worth the waste of time and money IMHO.
