well, it's not so much what changes the ecu will make, it's more what changes you should make to suit the fuel and ignition maps set in the unit by mines. See what they did is make some mods to a car eg. intercooler, pod filter, exhaust etc and then put the car on a dyno and then program the ecu to manage the optimum power for the mods they make to the engine. thesse mods are subtle and the programing is done by the famous mines workshop. you can email them just as i did and get all the details however you will need to add a fuel pressure reg, an exhaust with greater flow than standard, a larger intercooler will help and an unrestricive air filament such as a pod filter.
Just as a reminder, this this is dirt cheap!!! i had one guy throw me and offer and i jumped on it but he seems to have dissapeared.
