    Code 44 possibly due to leaning it out with Translator and FP regulator?

    Yes it is a closed loop idle chip. Is yours going into closed loop? What is the BL and INT doing when in closed loop?
    With a lean code I would suspect BL is pegged at 150. That would indicate a big vacuum leak. Make sure your static fuel pressure is set to 42psi.

    Do you have a shop vac? Hook it up in revers to the intake pipe. Use soapy water in a spray bottle to check for leaks post throttle body. EGR gaskets are notorious for leaking.

    You can do the same for exhaust leaks. Hook the vacuum to the tailpipe. If you have dual's, plug the other pipe with a towel or something. Check for pre turbo leaks on the headers.

    Ideally you BL should be within 10 +/- of 128.

    ok thanks. was wondering what state did emission testing, but did not care about EGR. (said he didn't have one)
