Message: [QUOTE="Fast-6.0, post: 640446, member: 353"] Keep in mind that when you gate around the VGT it will slow down and so will the atmosphere charger. Unless you are on a dyno or at the track you are guessing. 50psi boost with stock turbos in nowhere near the airflow that Max-Powers are at 40. Boost is far from everything. Your backpressure is at the VGT, the only way to use that excess backpressure is to feed it in between the stages. In your setup you dump it to the downpipe. So not an option. The Max-Power sets making 60+ psi are typically running larger nozzles and sometimes VGT tuning. I say tighten the gate up to let both chargers run harder. Sometimes in the quest for backpressure we dump the gate too early and the truck wont make as much power. You really only care about the backpressure numbers above 3000 rpm. Keep backpressure below 80psi is my suggestion. [/QUOTE]
