Can anyone help me with a tune on a 2001 2500hd 8.1l engine with the 5 speed allison trans? Looking for some pointers to help wake this thing up safely. Torque management or anything to take out? Also wondering about when towing and set cruise, get to a hill and it seems to downshift two gears and really jump in rpms, any way to get it to drop only one gear? Only happens in cruise it really jumps and almost scares ya when it kicks in. lol
