help with shift points for fuel economy

[smslyguy]

can anyone tell me what to adjust on a 2000 gmc, with a 01 o.s, for adjusting shift points or to lock up the torque converter sooner? I was hoping to sqeeze a couple extra m.p.g out of it if possible. I am currently getting 14-16 m.p.g, which is horrible. any help would be greatly appreciated.

what about a 2000 S10? Please?
its an Extreme so i wont be towing anything and i did the 0411 swap with the 02 OS, so i could use the Performance shift tables and hook a switch up to that pin to activate it?

Thanks,
Branden
