Patriot H-D in Fairfax offers Dyno service for $80/hr. Here's the link. But their service department leaves a lot to be desired so don't take this a recommendation. Grove's H-D in Winchester also has a Dyno and they seem much better in the service department.
Thanks for the info gents. Think I'll try Winchester. Haven't had a chance to get up there yet. I heard a dyno tune will get rid of some of the popping on deceleration. Can anyone confirm or deny that? Got a arlen ness big sucker, rev tech DFO and reinharts. Planning to get the remap sometome anyway (in case the DFO fails).
