    L29 454 Idle tuning assistance

    Looking for some help with this truck. I have basically this weekend to get it running good enough to try to drive from OH to NC the end of next week. If somebody is a tuner or you know a good guy that wants to assist and make a little money I'm fine with that too. From a previous thread I found I had no injector data to get a proper start and I found I had a warped intake which is now fixed and new AC Delco injectors and a new IAC that was bad. So I think I'm at a good stable place to begin again. Specs below, tune file and log attached that so far is just Injector data, RPM, idle base flow upped 20% and idle timing increased a little. So far that was just a cold start to about 85 degrees CLT. I'm hoping that's enough to get started on the cold start

    Specs are
    96 2ws Dually
    454 bored .030 over
    0411 PCM
    Comp Cams XR264HR-13 towing cam
    JBA Long Tube headers
    high flow cat
    magnaflow muffler 2 in 1 Out
    K&N short ram intake
    2173412.8 51lb Injectors
    4.10 gears
