Hi.
Ecutek remap with Andy F will be £600+. Thats what mine was a couple of years ago. Alot, but it does make the world of difference to the car.
Also worth considering would be Trackhound tuningwho is getting good reviews on here. Uses open source remapping I believe which means bout half the price but dont quote me. Ecutek costs alot due to the licence needed. Open source no licence required as far as i know.
Another vote for grooved discs. Goodridge and HEL for your braided hoses.
Just put mintex 1144 pads on the car, alot better than standard, sure your brembo pads, discs will be fine.
Cheers.
