Great find man. Honestly in my opinion I always felt best mod to start with is a tune. Something you can feel the difference in when you drive. It can also make the throttle a little more touchier for you. Also it will remove a lot of the truck's torque management and allow more power get down to the ground. Let me know if you have any questions we have the only aftermarket camshaft for them and we carry the better oil pump gears on these which is another common issue on the 6.2's.
