    It tunes and scans as an LS1B, and is that style with the blue and green connectors. I've looked through threads for most of the day and it appears that the '06 OS PIDs were a little neglected since...
  2. 2003 Suburban 8.1L/4l80E 4x4 tune

    I've attached the tune out of my stock 2003 suburban 8.1L 4L80e 4x4. It should be similar to what you need as the motors were very similar with return vacuum FPRs and EGR. The timing sets were...

    Yes, mine was originally a V8 2012. I've got the motor installed and running, but had to pay blackbear for a tune since I never was able to get a stock L9H tune much less an L92.
