Custom code normally advise a couple more mods before going for phase 2... don't know if it's the same for the cupra as the cupra R but they advise a front mount intercooler and uprated hoses (TIP etc) for that on top of what you already have... maybe you'd be better off with phase 1 at the moment or wait until you've gathered a few more bits. I have the phase 1 map and it is fantastic IMO, speak to the CC dealer or post on their SCN section for more advice.
