R-tech don't do switchable on stage 2+, I didn't get it or even offered it, I asked and was told they don't do it.
This whole thing about R-tech being custom and tailored to your car is great PR for them, but such a urban myth. You get about 3 hours on the dyno (they do 3 cars a day), which essentially entails them loading their 'generic map' then tweaking it to squeeze your car, not for drivability, but for max power. If you watch them tune there is zero part throttle tuning, you just get a series of full throttle runs to the limiter, that's not custom (I think I counted 5 runs total for my car) that's extracting every ounce from your car before the hardware you have can't do any more. Most of that 3 hours is taken with loading changes into the ecu.
They are priced well and know their stuff but to say they are custom maps is only partly true at best. I have had both RTech, revo, Superchips and APR maps, I know APR and Revo spend huge amounts of time and money on their maps for feel and drive ability, part and full throttle. For me revo was the best feeling map. As pudding said, too many people chase headline numbers.
Horses for courses, loads of people like rtech and they know their stuff, but not sure half of the people even try anything else as they just get told to 'go to rtech' ! No one can tune the TFSI. Revo drove better in my humble opinion
