I thought I would make a post to clarify a very common question.
How much do I need to add / subtract to make ____ change?
As a general rule of thumb, 10 points up or down is equal to 1 Air Fuel Ratio.
This is true if
-you are using the map with the intended setup
-you are using the intended injector size
-the O2 sensor is off while you are testing and tuning.
Things to remember while adjusting fuel
-If the O2 is on while you are doing this, you will have inconsistent results.
-Increased injector size may change how many points you must change to see a result.
