I think I will not go to stage 2. APR is already released Stage 2 and the difference using petrol at 98 octane is 10 CV compared to Stage 1.
I hypothesize that Revo also obtains the same maximum power values. It is likely that they will be able to get more torque at intermediate regimes. But this requires remaping DSG exceeding its 65 kgm limit.
If REVO will come out with a very pushed map on the advance as for Stage 2 of the PFL the octane 98 petrol will not be sufficient.
I think at this point the stage 1 +, with intercooler, cat 200 cells and a panel filter K & N is the right compromise.
