    nbs 2006 V6 to V8 swap

    Hey fellas, i'm having trouble with a V6 to V8 swap. I keep getting a "unlicensed vehicle" prompt. im using the V6 PCM. ive licensed the PCM and V6 tune (2 credits). I then had my tuner write a tune for it. the OS has been changed to a V8 and all the tuning work was done by him. I swapped the V6 VIN into the tune he provided and licensed this hybrid tune (another 2 credits) and attempted to flash it. it just gives me a unlicensed vehicle prompt. I read back in some old threads and guys were saying this is possible to do with 4 credits, but that doesn't seem to be the case for me. maybe im missing something simple? thanks

    Seems like you opened a can of worms trying to change the VIN again. The VIN means nothing unless you have to do emissions testing that actually look for it.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
