    What are you running for a tune? what are you running for ignition? What is this on NA or Turbo? Did you match your ecu to engine timing using the "guess way" as you said you would in your timing thread or did you do it the acurate way with part of the timing cover?

    Did you turn it off fixed timing? IAT, 02 and CTS calibrated?

          That was my thoughts as well, just wasn't too sure of myself I guess.

                  It comes with a short sock. You'll need to go back in and get the longer one.

                    Yup I kept the long one. My car sat a couple yrs with a bad pump, I changed it, then I decided to boost it and got a bigger pump. I kept long strainer
