I had a modded WRX with Cobb tunning through there Access Port Hand held up loader, and the nice thing about there up loader was they had stage 1 stage 2 and custom tunes. Lets forget about custom tunes right now, This would be the perfect Bully Dog, 6 maps available Economy , Towing , Valet , Stage 1 CAI and Cat back , Stage 2 CAI and Cat back and Headers , Stage 3 CAI and Cat back and Headers and Cams then later possibly Custom Tunes.
So with there Hand held down load the maps you want from there website and up load to your ECU as needed.
Progressive Tunes for Progressive Mods.
