I'm getting ready to install the 411 PCM into my Durango swap. I'd like to use a stock tune from a 2000 Silverado 2500 that came with the 5.3 and 4L80 to start out. Apparently this was a 1-year option. There's a tune in the repository with a 5.3 and 4L80 segment swap I'll use if this one is not available, but I wanted to ask first. I've spent some time looking for a VIN from a salvage truck so I could go the GM SPS route, but no luck. I'd need to confirm the options via the truck's VIN if possible. Thanks for any help.
