14th Jul 11 Hi Andrew, Good unit, installed easily too. The 4 different maps is very good. Initially I had the unit on Map1 (default) and although in gear pickup was vastly improved, I still had turbo lag low down in revs. Looking at the charts for the maps, Map 3 looked a more promising option as it starts early and gradually builds up low down at a quicker rate and right enough feels a lot better (35mile commute this morning), has reduced the lag quite a bit and in gear pull still there too. Has made the car a lot more “driveable”. If there was anything to comment on for future development, it may be worth a look at a map that starts producing power / winding up turbo as early as possible to get rid of the turbo lag as much as possible, doesnt have to be full on power, I think so it starts producing power earlier would be the key. I will pass on the good word on the Juke forum so you might get a few more sales. Regards, Aaron
