Yes, not a problem at all. I'm Revo based with my ECU tuning and ran the GIAC DSG remap before the Revo Stage 2 map became availble, when I changed. No problems at all. With this considered the feel of Revo on Revo is better as the shift points on the DSG map are optimised for Revo tuning, am guessing that this is also case with GIAC. Products are not mutually exclusive though.
