yes mate they do come with the maps well the stratagem does anyway it has three rs performnce' race and race+ you can also change the boost settings via the unit and the spark advance to plus 2 degrees it says on the advertisment the maps or programs take it on rs performance to 235 bhp and on the race+ upto 334 bhp but i havent had mine on the rollers but it feels soo much better. you can also get the ds 3000 unit that is more or less the same as the stratagem but that does not have any maps on it so you have to pay extra for a live map. but the beauty of the stratagem is you get three maps to start you off with basic mods then when you start going mad with mods you can format the stratagem at a master dealer so that it does the same as the ds 3000 and then either live map it or tell them what mods you have done and they will email you a new map to upload onto your unit
