I have the Banks CAI on my '05 Z-71, 5.3. Its great,nicest CAI I've ever had. Haven't tried the OttoMind, I run the Diablo Preditor. I e-mailed Banks about comparisons between the Diablo and the OttoMind and I never got a response. From what I've read it doesn't let you adjust the LongTermFuelTrims, the Diablo does and making these adjustments help the mpg's, throttleresponse and performance.
