From the guy who made the chip:
it costs £241.99 including VAT P&P
it does:
imporoves drivability
improves mpg by about 10 MPG
improves torque through out the range
eliminates a few flat-spots in the existing ECU.
invalidate your warranty
is not detectable at service
it does not:
give you better braking (joke) however, R-sport are bringing out a complete brake upgrade later in the year.
give you the opportunity to beat Scoobies
give you AWD (4x4)
it does not give you bigger bolx to go around that corner a bit quicker.
and it doesnt make you more attractive to the opposite sex.
