Will the flow characteristics of this setup be different enough from a 3" exhaust to throw things off, or will it be fine? The free stage 1 map here runs well. I tried the free stage 2 and it gave me overboost followed immediately by boost oscillation at high load, but I think I probably could have gotten rid of that by readjusting my wastegate arm.
Other questions - the purchased map is still tunable with RomRaider, right? Is there much support for fine-tuning once the map is purchased?
