Ive dropped an email but does anyone know the cost going from an r-tech stg1 to stg2 with them?
Definately ring them up mate and keep trying until your booked in. Usually around a 3 or 4 week wait. I just had a custom stage 1 map with pre cat delete, cat back exhaust and pipercross filter. Made 205 bhp after the initial dyno run and 255 bhp after mapping
