A external wastegate is needed to bring down your drive pressure and ETG's (Exhaust gas temperature). The more modifications you make the more likely you will need a external wastegate. I started to have high ETG's so I installed a drive pressure gauge and then I could see why, my drive pressure was a lot higher the my Boost. So I installed a external wastegate. I have the wastegate installed before my first turbo and it is wastegated to my primary turbo. The external wastegate made a big differnce, now I can tell when my wastegate opens my drive pressure stays close to my Boost pressure.
