If you've got a laptop and a cable (about a fiver from ebay) you can do it yourself in about half an hour. You'll need to download a program called Tuneecu and maps are available online (loads for the Thunderbird on www.thunderbird1600.com) All the instructions you need are on the Thunderbird forum too. Hope this helps (and saves you a few bob too) :upyeah:
Thanks for the tip Shagrat, the bike is only 3 months old so still under warranty, I phoned Performance Triumph in Cheltenham to book it in for it's 1st service and I asked how much for a remap, they said they will do it for free :upyeah: happy days :upyeah:
