Smitty, the DigiCr goes into the fuel rail line via a Y cable. I do not think it makes any boost changes. I don't think it claims to either. I have not noticed an increase in boost pressure. I can tell you it really wakes the engine up.
I cannot run mine on the highest setting or the engine will go into the limp mode and need to be restarted to reset things. They were able to dyno it on the highest setting but I just can't run it that high in the real world. I run on 8-9. On a rare occasion it will go into limp mode on 9. It could be filters needing to be changed when it does that. It is only when I hammer down to the floor that it acts that way and only while accelerating up to speed. I has not done it at highway speeds running up a hill for example.
