Coolmex's review on his other car: http://f30.bimmerpost.com/forums/sho....php?t=1026299

The fact that he went from 0 to 4 and and no improvement in EcoPro lag doesn't seem very good to me. RaceChip lag is virtually improved when you increase the settings to my knowledge. He also declined from ~24mpg to 21mpg while many have noted improvement in mpg slightly with RaceChip. I'm not sure anything will be accurate without someone testing both on their car. I'll look for more reviews and post .
