Hey abo,
that car has a 2540!! anyway, besides that, i just want to say that i believe the dyno at unigroup reads higher than others, as an example, i ran my old gts-t on the dyno there it only had a catback(with a 2.5" muffler in the middle to remove defect) and a panel filter, stock everything else, and it pulled 165rwkw shootout mode.
on the same day (group dyno day) i saw ~6 na z32s(with small mods) pull ~130-135rwkw, which i thought was too high, as gtst-s make that kind of power when not much far from stock. i was thinking crap my car is only as powerful as an n/a z32, until i ran it
so the 209rwkw with stock computer may be a bit misleading when comparing with other dynos.
