hi all i was wondering what advantages i would see on a remap on my 535d 2006,i promised myself i wouldn't but if the price was good and so were the advantages i might convince myself.also can anyone recommend a top firm in the north east area with a rough guide to price power and fuel changes,I've seen a few e.g from 500 too 600nm torque but i thought my car had 413nm so it all left me a little confused
