just had my 500 remapped by tom from angel.
he doesnt just map the car but gives you loads of advise and tips whilst he is doing it.
he really knows these cars inside out and i learned so much from spending an hour with him.
and as a bonus i got a superb remap at the same time, the car has come alive and it wasnt exactly sluggish beforehand.
speak to angel , you wont regret it.
