I never had my car dyno'd, so I can't tell you hard numbers. I can tell you seat of the pants feel, and that was immediately noticeable, as well as improved MPG, approx 1.5-2 more. I was disappointed that some of the earlier function have been removed. It could also use better prompts when updating and installing, but mainly overall pleased.
