that's about weird...they should have done a dualtwincharge not that setup, twin charge=supercharger use until turbo spools, dualtwincharge=supercharger use til 1st turbo spools, 1st turbo use til 2nd turbo spools, and i have no fu c king clue what it's actually called i just always called it dualtwincharged hahhaa. i know it's called twincharged on the 1st one though.
