    v6 4.3 to v8 6.0

    A customer has a 03 sierra originally a 4.3 and we are swapping a 6.0 lq4 in it. What i need to know if its possible to do a engine segment swap in the same pcm. Ive done a few trans segment swaps but never heard of a engine segment swap. I already found a tune with the same OS id but i dont want to buy credits for it before im sure it can be done. Thanks.

    If the 2 cals have the same OS you should be able to swap any segments they have. At least I can with some other tuning software I have. I don't have HPT 2.25 so I haven't seen how they do it. There are some 03 4.3 and 6.0 files that both use OS 12579405.

    Yup they both have 12579405. So the v6 pcm has all the hardware inside ready to accept a v8?
