The fuel system consist of 2 extra injectors and tsi controller.
The controller can add fuel under boost and it can also add fuel by rpm (like Apexi safc-II)

I might be wrong, and thats why I'm asking.
As I think - no boost, no more fuel needed than stock, going into boost - more fuel as psi increases.

1 Am I wrong with not having rpm fuel enrichment?

2 Why whould I want to be adding more fuel to the engine at times when my boost in vacuum (e.g cruising, constant speed)?

you are right. if you are using the PSI settings on the TSI controller you dont want to use the RPM ones as well. It makes the car run like ***.

But if you are running low comp pistons and a high lobe cam and no other engine managment then you would want to add a little more fuel at the rpm settings. Once the controller reads boost it changes from the rpm settings to the psi settings. then goes back once in vacumme.

Ok, I've reset all RPM setting to zero and adjusted fuel voluem by boost.
Car does feel better now, in fact, it drives much better now!
Thanks Chief.
