Hi Dani,
I too have a 'stage 2' cupra which, according to my dyno graph produces 24psi
at 3300 revs then sits in the 20+psi range until 4800 revs, then falls off to 12psi at 6600 revs.
comparing this to my boost gauge, it isn't too far off but its tricky driving with one eye on the road lol.
I wouldn't worry too much about it, these are 13+ year old cars,
they won't perform like new,regardless of mileage or ECU mappage.
