Had mine on the rollers at MRC yesterday and stock figures were 310 BHP, so that was down 14 BHP on the "book" figure and it was 656 Nm (484 lb/ft), so that was up by 6 Nm on the "book" figure.
Readings after remap and gearbox flash were 360 BHP (+ 50 BHP) and 807 Nm (595 lb ft) (+ 151 Nm). Nice increase for a quick remap. It has certainly changed the character of the car for the better. Pulls like a steam train now and is a lot quicker on the pickup. The acceleration seems smoother too. This is more like I expected the car to perform when I first got it. Well worth doing and the guys at MRC really know their stuff.
