They did the whole show on upgrading a Duramax with BD parts. Showed changing the valve body and torque convertor on the Allison. New Turbo, Exhuaust and exhuast manifod on the left side. When done they put in on the dyno and it cranked out 502 hp and 970 pounds of torque at the rear wheels.
Pretty interesting show. The showed some cutaways of the stock parts vs. the aftermarket parts.
