I know I got some good mileage by lowering all of my shift points on the canned tunes. I think I also lowered the idle a little bit. That brought my city up from 10-13 up to the 13-16 range. Im not so sure about my cutom tune though, now I'm getting about 13 city. I think my mileage went back down because the shift points are higher rather than lower than stock.

The 97-03 firmware only supports raising the Idle speed, not lowering it. Unfortunately, the 97-03 firmware is a bit more complicated because of the communications structure between the programmer unit and the "smart" cable. It makes it difficult to make certain changes in the firmware which is why the 97-03 doesn't have all the fancy stuff that the 04-08 does. It's one of those things that we do want to get updated, but because of the time and complexity involved, I need a week of peace and quiet to effect those changes. Until then, it's all we've got.
Hope that makes sense.

Bill, freeway economy tune ??
Hey Bill,
As for an economy tune for freeway driving, can a program be written that would cut fuel to 2 cylinders to improve fuel mileage on the road. Maybe something that would work in correlation with engine load. Thanks, Mike
