Right now, my 2002 S10 has the 0411 PCM and I am in the process of swapping out the 4.3 for the 5.7 Vortec. I'm trying to keep this install as "EPA/NY" clean as possible, which means I have to match 2002 5.7 emissions for NY inspection. Now, NY is a PITA, and my PCM vin must match the registration vin before it will pass inspection. Here are my questions...
1. I need a 2002 Chevrolet Express 5.7 tune?
2. Once I have the tune, do I simply make whatever changes I need to make and do the vin change at the same time?
3. Then do a "write entire"?
4. How many credits will this use? The current 4.3 file is already licensed.
