    Looking for XDF file for 03 lq9

    I have a 03 lq9 out of a Cadillac escalade being swapped in a drift car, im looking for a xdf file that will work with the ecu and motor, im trying to delete vats and probably DBW, also be running a t56 instead of the auto it originally had. Thank you in advance.

    You will need a different PCM if you want to go back to a cable throttle. There's no IAC driver in that PCM since it was meant for DBW. You'll either need a PCM out of an 03+ express van, S10, S10 blazer, or full size truck with a 4.3l to run DBC. Or you can go back to an 0411 PCM which has LOTS of support.
