    Bandit,

    Welcome to the forum...

    Your current tune file is GM OS 12212156...

    Here's a plan:
    1. copy/edit various tables from Bruce's tune file;
    2. use the spreadsheet to calculate your IFR table;
    3. increase trans. shift pressures (see images);
    4. install your wideband and verify that it reads correctly;
    5. do the AutoVE tune procedure (see AutoVE tutorial);
    6. at this point you're in OLSD, see how it runs (MAF-less);
    7. install COS5: showthread.php?p=52999#post52999 post #228, see how it runs (MAF-less);
    8. tune idle: showthread.php?t=4661
    9. tweak shift points and shift times;
    11. install MAF and auto tune MAF table (similar procedure to AutoVE tune);

    Edit: There might be other steps to insert.

    Sounds like a lot, but you should be able to progress thruu all that quickly.

    Some tables you can copy from HPT to spreadsheet and then into EFILive.

    Thanks for the insight I think I am gunna wait for bruce to send me the file he said he'd share with me so i can look a it and see where I am off so bad. I even tried downloading the tuners tune again to see if it just needed to reset somehow but nope ran so bad everytime I gave it gas it backfired and popped. Trans was shifting erratically and torque converter setting are whack cause the car was jerking ALOT. I simply installed my tune from HPtuners and the car ran great except for the trans and TCC setting which for some reason i cant get right. Anyone who is a god with tuning big cam big engines want to take a flight to Utah for a day or 2 Im buying!!!! Sad thing is Im serious as I plan on either flying in someone willing or something to get this right I dont have the time to learn at this point I have to get back in the points races or lose and Ive missed too much already
