S4 Turbo what PSI is most efficent, for the most power?
Just wondering before I have to go to the dyno, I realise that more boost doesn't always make more power, just wondering from your experience, I realis it will be differnt for diff intercooler exhaust setups but what is generally a good psi for losta power 12,13,14,15? I will most likly be getting a BNR upgrade soon and I know it won't last very long at that pressure...

The limit for the stock turbocharger seems to be 13-15psi. Anything more and you are overspinning/overheating the turbocharger and not making any more power really. It's uncomman to seem someone above 14 psi.
