What controls the shift points? Is it a TPS, or Manifold Pressure, or combination. I would like for my Equinox to upshift a little earlier. I noticed when I am below 40 mph that the RPM indicates I am in a lower gear, and my instantaneous fuel economy is way down. When I can get it to upshift, the fuel economy goes way up. I realize this would hurt the performance a little, but I can always push the throttle further down, if I need it.

Don't want to get into a big deal, but if I could just tweak the TPS, I might give it a try. ;D
