I can't speak highly enough of the Burger JB4, plug it in, takes about 20 minutes, then drive and enjoy. Even on the basic Pump 98 map the difference is beyond what I thought possible. We have the bluetooth module and the data cable for the laptop. After a bit of logging on the higher maps I emailed the data to George and he suggested a few minor changes for the step up maps.
Since it's plug in it is very easy to remove for servicing, warranty and insurance claims if necessary. All of my cars are insured with Shannons, so mods are not an issue.
Cheers
