It wasn't RR'd but the AT guy had his little computer thingymajig that gave you the 0-60, 0-80 times etc. and also the bhp figure. On mine after the remap it was 132bhp And he reckons that the torque would increase around 30%, which would make it around 190lb/ft
My advice to you is...... GET IT DONE!!!!! It drives much much smoother and revs nicely for a diesel too
