Dear Chris,
We offer one for the 8v, which my car runs currently, these we offer via this forum under the trader section and also on ebay.
The chip is mapped to deliver the following, smoother torque curve, injection pulse rate changed to minimise the digi-lag syndrome and then the fueling is changed past 4500rpm, standard e-prom leans the fuelling after 4500rpm, at which point the engine gets more air then fuel and end result being less power.
Our chip are aimed at drivability (torque), you will notice the day to day runs a little smoother with slightley improved fuel economy.
If a rolling road day is sorted out via the club then we will be able to offer a before and after map, we can send you the 3D graph of how the chip is re-mapped, so you can see the gains on paper.
The later you would be looking at a later stage of tune.
Please note that our chips are not the basic resistor type offering, which you may see of find else where, we can also offer a custom mapping service to the car but the costs change at this point, lot more time involved.ÂÂÂ
