Yep - i take my bikes there too (only 20 mins away) - hes done my hypermotard (last year) runs brilliantly. He did my z1000 a couple of years back...loads of restrictions in there that were removed - goes like a rocket - ive changed the exhaust around to a different configuration and drilled the airbox so its going back in next week for a remap. Another lad on the zed forum took his there on tuesday. He was more than chuffed! Spoke to my mate on the phone when i got back to work (the one with the scrambler) - says it feels like a different bike (i think he's out on it tomorrow for the day) I wouldnt take my bikes anywhere else.
I spoke to my dealer earlier in the month who does a fair bit on dyne work and they said the same as the guys on here, haven't cracked on yet. Also mentioned something about whenever it gets plugged in any mapping will be reset?? Will also add, I had a sprint air filter installed to match the arrow decat and it hugely improved the fuelling to the point it feels as if its been tuned. Would highly recommend, my air filter was also filthy after 9000 miles!
Not sure if i read somewhere that Hilltop were working on a upgrade for DVT but i think if you go it will be Guinipig time. Just saying.
