I used this to tune in my carb, it worked great, then my wife gave me a EFI system. I actually debated about returning the EFI because the carb was tuned so well. The EFI came with its own a/f function so there is no reason to keep this one too. I also was able to reuse my o2 sensor bung so I included the one from the EFI which can be hose clamped on or welded. Worked great, just not needed any more.
