I am not sure what "AEM WAI" is but unless it is NOS I cannot see how 450whp (=330kW atw) is possible with stock turbos.Well my aim is 450 whp, with supporting mods and stock turbo, I assume with 1,5 bar boost (max td03 turbo can be achieved) i am still believing it is not impossible. I am not chasing huge horse power. No E85 in my country the best is 100 ron (very exPensive) and 95 RON. I am counting on RON 95 + AEM WAI
