How to tune without guessing

If you have ever tuned a carburetor or EFI system you know how difficult and time-consuming it can be. Take the guesswork out of tuning by using an O2 sensor. Dobeck performance has what they call their SAFR tool. This makes tuning without a dyno possible. We like to set out AFR or air fuel ratio to 12.5-13.5. If you are trying to get the best gas mileage possible say around the 14.7 mark. Here is a link to the tool:
