Hey guys I'm looking to get an answer of what the preferred injection quantity should be ? Can anyone advise me on what it should be ? I changed my gaskets because my pump was leaking and I'm taking my car to a shop because I don't have a vag com so can anyone help me out on that ?

If it's all stock, it will run around 2.2 to 2.8. Many folks believe this is too rich, mine always ran fine. Now that I'm tuned it sits at 4.

They say for optimum MPG, it's around 5, but every car is different, so try 4 and go from there. If the mpg and power is good, little smoke, then your good to go.

What I meant was wouldn't I be able to set it to the same Injection quantity it had before I changed the gaskets ?

Unless you checked it before you took it apart, you won't know what it was. Also, if you did note it, doesn't matter as you moved the top piece ala the hammer mod so that changes it too.
