Just wanted to say thanks for everyone's help. I also tried the line off of the throttle body with no avail (Somebody on another forum used that line with another kit). The circuitry is correct because I can start the pump by pushing the microswitch with a scribe. Its just there seems not to be enough pressure pushing on the piston to move it under boost.
I've gone ahead and ordered the
Progressive Controller (which now that I reflect on it is what I should have ordered in the first place).
Chance, I couldn't remember what MAP sensor stock '04 SRT 4s' come with (I think its a 2.0bar. Stage 2/3 kits come with a 3.0 bar if I remember correctly), so I just ordered the voltage controller. But if you wouldn't mind, could you double check my order?
