No software etc, just a obd 2 box from machien mart. got it purely to turn off management light. There are a few variables to change on the box you see, boost and revs. Its taken alot of playing to get it where it is now, I think I have it sorted now. Im doing a big drive today, about 300 miles so by the end I will know for sure that its set up ok. So tomorrow I will doa few review. What I can say is that it feels as quick as my mates leon which is 280bhp. It picks up much more aggressively and is smooth all the way up to red line. Been a lot of work but very happy
