I have tried the search but can't seem to find anything. I'm hoping one of you guys could get me going here or at least point me in the right direction.
I have a 99-02 5.7L/4L60E that I have swapped into my 70 Z28. I have a 0411 PCM from an 2002 5.3L truck that I plan to use with this. I need to change my PCM from 5.3 to 5.7. How do I do this? I have had HPT for years and used it a lot, but nothing to this extent. I would appreciate any help or advice.
