First off - it should say "Boz", not "Box". Stupid autocorrect.
But I have had Harleys tuned at many places in the UK over the years and Boz just manages to get more out of them than most. Most of the other tuning shops that do Harleys, don't do many Harleys compared to other makes and Boz really knows his stuff.
He's written quite a few articles for "American V" magazine and if you can find back issues and have a read, his experience comes through well. He's also very well versed in custom engine builds from old Pans and Shovels right up to the current M8s. He's been recommended to me by several custom builders and HD dealers over the years.
But - he uses a tuning system called "Direct Link" which is not compatible with your typical Harley or Power Commander/Power Vision systems (which is why I said have a chat with him before you splash out money for a tuner). The resolution on Direct Link is (apparently) finer than that on most other systems. Most tuners will just stick an O2 sniffer up your tail pipe, whereas Boz will pull the heat shields off the pipes, drill holes in the right place in the header, set a rivnut type thing in and then screw the O2 sensors in that to get them in exactly the right place in the gas flow.
On my current M8 114" with the HD Stage 2 Torque cam and a Bassani Road Rage 3 I am getting 110HP and 126 at the rear wheel on his dyno.....which is pretty bloody for that setup with the limitation of the HD EPA compliant cam.
Anyway - in my opinion if you are looking to have a Harley properly tuned, call V-Twin and have a chat with Nick and Boz. Its worth your time to get things done correctly the first time!
