I had a hard time downloading, until I called the tech support, the instructions was simple and worked. I loaded stage 3 setting the mpg increased 15-19 city and 15-24 hwy after it warm-up. I noticed the new life in all around performance immediately.

Regained my mpg and calibrated my speedometer after installing larger tires. Cleared rough idle as well. Tech Dept helped with calibration of speedometer (use actual measured tire height not calculated height)
