You'll have to read the full story for an explanation of the artificially low torque figures of the tuned Regal, but we began the dyno thrashing with the stock baseline against the bolt-ons and stock pulley. The intake, ECU and full exhaust relieved restriction and dropped boost from a figured of just over 9 psi to only 7.5 psi. Despite the drop in boost, power increased by 28hp at the wheels.
