questions about programming and BCM failures

[philosch]

I have a 2016 Colorado 3.6l Crew Cab bought new in December 2016. Had the typical bad shift characteristics and underwhelming low end performance so I put a Trifecta program on the truck and it ran beautiful for 4 months. Even got a verified 29mpg on a 400 mile trip. Outstanding performance. Then after 4 months the BCM completely failed. I had to have the truck dragged onto a flatbed because we couldn’t even get it into neutral. The dealer replaced the BCM under warranty with no issue. I had reflashed the truck back to stock before the warranty work and have now reprogrammed it back with the Trifecta tune. It’s running fine. My questions are, is it possible that programming the vehicle originally using my laptop on battery power could have damaged the BCM even though it ran for 4 months ok afterwards? If that’s not an issue then what’s the likelihood that the BCM will fail again? Lastly, would it be possible to have a spare BCM programmed and kept as a spare so I don’t get stranded like that again? It really chaps my A5%$#%^SS that I now have to worry that this $38,000 truck can leave me stranded at any moment. Anyone got any suggestions or comments?

BCM's don't often but they do on occasion. Not likely related to your programming. Drive it and stop worrying.
