NO you do NOT want to do that even if there is a chip for it. The ISL is already at the max torque for the 3000 Allison tranny...1200 ftlbs. If you look at the torque curve you will see they are already limiting the ISL's torque...flat at1200 ftlbs between 1100-1600 RPMs instead of a curve up to 1300+.
You need to learn to anticipate when you need more power...do not use the cruise except on fairly flat ground. Do not wait until you are part way up a hill before going to 100% power. At the bottom of a hill when I can see ahead in hilly terrain, I will be 5-8 mph above my normal cruise speed with the pedal to the metal. Also, do not haul around 800 lbs of water if you do not need it.
