And also when i change the settings back to the tuned settings does the car take affect to air fuel changes right away or does the ecu take time to recognize again??

I believe the setting of the VAFC only activate at Wide Open throttle...Its set on the VAFC as Hi and Low. But I could be wrong.

I don't think there is a problem from going stock to tuned, just as long as you save the tuned numbers.

Assuming your V-AFC is set up and tuned correctly (no fuel corrections when throttle is not wide open), then just write the settings down and do whatever you want. Whenever you want to put them back in, just do it.

Why would you want to put it back to stock anyway?
