> What are you talking about? Stage one is simple reflash, stage 2 requires intake, turbo back exhaust including downpipe, and 4 bar FPR if we are talking about your GTI. Stage 3 is BIG TURBO software which depending on brand- can be tuned to specific setups (atleast REVO can) so don’t quote that.

exactly what I said.

I know off the top of my head, as I had apr tuning on my gti mk5.  
stage 1 reflash adds 50hp and 100ft/lbs to the crank. (dyno proven obv)  
stage 2 from what I heard adds another 40+ hp. but you need a full exhaust,intake and bigger fuel pump
