Nah i went to them mate, cost me £250, they themselves never rolling roaded my car however they showed me revies on fabia vrs, and
ibiza fr/sports gains, minimum 179 i think.... on one of the cars, and i think there was a few that kicked over the 190 on the rolling road, i did however get a rolling road done locally, which cost a bit of a fortune for a bit of paper lol, mine kicks out 187bhp and 309 ftlbs of torque. EMmmm ive had a few goes against different cars (on private roads obviously). My m8 has a
seat ibiza cupra petrol 180, and weve had a lot of extended goes against each other, against him i always pull away a couple of car lengths, and in a relatively straight road he'll keep within the 2 car lengths, however coming off roundabouts and taking over you then begin to see the difference and the remapped fr pulls away further, also up hill i have a good edge over him. Civic type r (old shape) you will take in the mid range, after 115-120 they catch back up and take you. CLio 182 is a hard one, they are fast wee cars, up hill u will have them. i found mid range u have the edge but both putting foot flat down after 80 its even stevens. Standard fabia vrs (friends car) u will have not a lot of bother with, same goes for c2 vts, fiesta st. In my experience.
