Anyone who is considering getting there diesel mapped, do it, you wont regret it.
First thing i did to my Bora when i got it was whack the Genius software on.
Deffo noticable difference in the way the car drives, holds the power alot more at the top end, bigger punch. Also better fuel economy when driven normally, so win win.
It made 173bhp and 311lb/ft on the dyno aswell, got to love the silly amounts of torque!
