Very basic description would be that :
Stage 1 needs no mods just the remap
Stage 2 is just needs the addition downpipe and remap
Stage 2+ is just the addition of a HPFP
At any time you can add an intercooler and ofcourse an intake which would both maximise the gains if you went above stage 1
Sounds like they don't know what they are talking about if they've only done a stage 1 map to your car and now say there is nothing left to do
