I have been playing with fuel injected systems, and its interesting to note how a car learns how to mix air and fuel after the computer is reset(disconnected the negative battery lead for a couple minutes). It gets lean, rich, spits out water, then normalizes.
I have an older fuel injection system that take 10-20 minutes to relearn the fuel mixture, and a couple of newer ones that take no more than 5.
I just wanna point this out to those that might not have done this regarding adding a booster to a fuel injection system. Something to try is resetting the ECM, and starting the car with the booster from the get go, making it part of the computers relearning process.
