As Neil and Dan have stated some early cars didnt 'make' the quoted figures.
The latest 'CJ' calibration seems to have cured those with missing horse's.
Incidently mine is an early car and I have had all the revised calibrations from CF onwards and upto CJ. However the car was definately more aggressive on its original 'CD' file upon my car.
As she has only done a couple of thousand mile and yet to see rain (Sad fooker I know

) it will be some time before I through her on the old rolling road lottery.
I was all up for the Mountune conversion at some point but until their 'calibration' issue is sorted I will be waiting. Failing that when she is out of warranty I may look down the Autotech route via JW Racing as they certainly seem to be delivering the goods at the moment and will certain only get better with further development.
