    Ok, I found the info. Everything is basically the same for spec c my05 and my06 engine wise, except exhaust before and after turbo. So basically in stock form my05 exhaust is calculated for 1.27bar @ 4000rpm and my06 exhaust is for 1.33bar @ 4000rpm from factory. And to answer my question - it is useless to upgrade my05 ecu without exhaust upgrade, because it wouldn't reach target boost, as I have already tested it. :)
