a stage 2 GTI/Rocco is completely different in terms of power delivery to a Stage 1 Ed30/Pirelli, whilst i loved my the Rocco in Stage 2 tune given it was more linear through the range compared to when it was Stage 1 it never matched the fun factor of the Pirelli hitting peak power higher up the range which for me made it more enjoyable to drive despite in some ways it no being as flexible given coming on boost later
this decision was confirmed when i drove an APR mapped rocco and actually preferred the my standard Ed35
Ed35 edges the Pirelli for me all day long (both ran the same tune for a while) except for the climate control which is way to fussy (unlike mk5 and later mk6 one)
