When you say they are "running out of range", what does that mean and how are you measuring? A common thing that a lot of folks to incorrectly is to review these readings at idle and that doesn't tell the correct story.

Drive the car and watch the numbers under load. I have a WiFi dongle that I pair to TrackAddict on my phone. With that, I can record a diag session to play back later. Set it up, press Record, and head out for a drive. You want to be able to capture data accelerating and holding speed at highway speeds (if possible). Flat roads where you can set the cruise control to anywhere from 45 to 65 for a short bit at least will get you some good long term numbers.

It's extremely common for the numbers to be negative... That's ok as long as they don't run way down and stay there solid.
