Short un-equal twin scroll design will narrow the gap of effectiveness when compared to a tuned system but the tuned system still has each pulse arriving in order. The twin scroll turbo has only one common shaft so cannot act independent. Off-boost torque is also improved with a tuned system. You don't want to be on boost in a street car tooling around town as fuel mileage will be horrific. Race cars are a different story with different design constraints.
This system we put together combines all of the above, tuned primaries and secondaries, split plenum for use with twin scroll turbo and dual wast gates that isolate each bank of cylinders. Many applications and options, this is just one.
