Superchip shift points

[braduardo]

I've got a 98 EB w/5.4l and I recently installed a Superchip Max Micro tuner. Are the "superchip" shift points pretty good to help with my mileage, or should I tweak them a bit? Most of my driving is in-town/city-hwy. I've noticed the truck seems to be a bit of a dog when trying to accelerate from lower (40-45mph) speed to highway speeds without really stepping on it to force it to downshift.

Any ideas?

My 4.6 regained the lost 1 L/100k putting it from 18.5 to 17.4 average running the tune with stock shiftpoints. It may be hard to accelerate from 40mph because the torque converter is likely locked in 4th. If you give it gas quickly it'll downshift earlier most likely. Other than that it likely won't make a difference.
