The lower idle speed is nothing more then something I noticed immediately on the tach. All other values including the engine temperature remain unchanged at "normal". The extended running time for the fan I haven't noticed but apparently is listed among the improvements....all in all no regrets. IMHO tweaking software is a more elegant way of modifying a cars performance compared to hardware changes. If you have the spare cash....go for it!
