Remember that dyno's are only a measuring tool. I've personally used mustang, dynojet, and superflow dyno's. The mustang's and superflow's allow you to add in LOAD which typically benefits turbo setups. More load creates more psi and torque at the spike on the bottom. Remember this is just of .5 second and it immediatly drops more into the normal range. I normally look at the 3500-4500 rpms range to see the realistic torque on these types of dyno's.
But, great overall numbers Man! Cars' a beast.
