I think the post regardign R tech sums it up, theres a standard list whether you have AGU , AUM, AUQ ,BAM etc etc, that you need to buy to get your car to the correct power,, people telling you you can get 220 bhp from 150 hp standard with just a 007p and remap are talking crap, takes a fair bit of time and money to see that 250 bhp figure that everyone seems to crave !
