So all the mods you've recently done added .8 bhp. That's ok. (everything else being equal)
Did they get the MPH off the roller spinning? Because the wind resistance on the road will have a huge effect on the top speed.

Re: Dyno tomaro
Aren't they supposed to pull the clutch in after the pull to calculate drive train losses as it spins down?
(i don't know how that machine works)
