My mate booked himself in at Horsham for a remap for his birthday and I couldn't resist tagging along to get mine done too, so we got there for 09:00am this morning. We were both impressed by each others results (he might post his up later as hes a member too).
2004 DE, 41k miles
Mods: Ark Grip true dual exhaust (Cat back), Pipercross panel filter, Flyboys velocity mod, Samco hose (standard airbox), Horsham Plenum Spacer.
I asked them to record a video for me (as you aren't allowed in the room now during dyno) but its come out vertical, oh well.
Now to recover from the 6hrs driving. Overall very happy with that
