Start/Setup a career in SH3 with the XXI, load your first mission but exit to base straight away. Then go into 'My Documents' and find the Patrol_0.cfg file inside your save folder, open it and edit the 'Deltarenown' to any figure you like. This will edit your starting renown so you can pimp your ride. There is another Patrol.cfg inside your save folder edit this one too to read the same. By default they are the last 2 files listed in your save folder.
