If this is possible, I'd like to build this thread for reference and maybe a sticky. With the ease of adding torque to the already torquey 3.0 a 400 maximum torque input seems shallow.

Can this be done? -Bell housing/FCM/TCM/ECU Flash?

Are you sure 580 has higher torque rating?

How about helping me replace ring and pinions to ~3.45 to drop freeway rpm 400 rpm, or so? How do I change axle ratios in transmission control box, if needed?
