I thought that the high flowed rb25det turbos were a lot more responsive than the stock one? Would that mean better low end torque?

Greater amount of energy is required to turn larger wheels up to speed, there for laggier. However bigger wheels are capable of flowing greater amount of air through both housings, let the engine burn more fuel and makes more power that way.

That makes sense.

Got my 34 gtt dyno tuned with the G3 turbo (the one rated for 450). Dyno reads 8% lower than actual numbers. Car made 309 whp on 14 psi. Stock manifolds. 650 injectors. Walbro pump. Mac valve boost controller. Haltech ecu.
