There's some great things said about R-Tech ,raving reviews ,and usually a waiting list of over a month to get a custom mapping. he does work wonders with the tfsi and will advise you if you are wanting stage 2 /2+ what mods are needed first . always gives the cars a full health check and wont map a car without any problems found been corrected first .
doubt you will find any negative comments about them. nephew had his seat leon cupra 11plate mapped stage 2+ with mods , forgot torque figures but come home with 364 bhp afterwards.
