How much boost are you planning for? And how are you planning to control the additional injectors?

The location should be in a place where is will not cause the fuel to form droplets or.. remain in the intake passage because of the risk of a back fire . I'm not familiar with the M104 but generally the location should be under the throttle body.

Personally I would go with 2 injectors for safety sake, say your under boost and one injector fails you will not lean out as much as if the failed injector is the only one you have. Better have it and not need it than need it and not have it.

Why are you using extra injectors? Why not install larger injectors to replace the factory injectors and add a programmable fuel injection computer?

1. There is only 1 shop here in my town who good enough to program the F-CON to work with our Mercedes and I don't like the idea of "NO CHOICE" with this simple setup I still can go to standard Mercedes shop to maintenance my car since i leave the OEM hfm as it is.

2. This additional injector system sound very simple to me. Just 1 vacuum +1 RPM signal which I think I can maintenance it in the future. I don't want to go to a Turboshop every time something wrong with the setup( sorry I forgot to tell u that I am such a noob compare to you people )

3. I am following Mr. RBYCC setup since his setup already prove to me how reliable it is. (and he is such a patiently guy who always help answering my (noob) question.

big thanks all of u
