Absolutely, both of those issues have been covered in our running MK6 stage 1 & 2 tunes. We recently took our Golf R IE450T development car and our IE stage 2 tuned MK6 DSG car on a 2100 mile 4 day trip through the mountains, desert, sea level coast, and array of climate and altitude conditions for over-all hardware and tune testing in any area. Both cars performed incredible with zero issues and made the long trip a real blast. I personally drove our Stage 2 MK6 for the majority of the trip, it was incredibly fun through the red wood lined twisty roads of Lake Tahoe, through the canyons, and along the Pacific coast highway. At the same time it was easy and comfortable to drive through busy streets in San Francisco and Las Vegas. No hiccups, plenty of power in any gear, very responsive, and the torque would break the snow tires loose in pretty much any gear below 5th. We have a ton of local customer cars running our Stage 1 & 2 tunes here in SLC, and we are getting ready to roll out flashing options nation wide here as soon as possible.
