H&S LML Issues Need Help

[chase81301]

We have a customer that is using an H&S. The customer was attempting to tune a 2014 Chevy with the tuner but it froze on 3 of 9 at 17%. He didn't know any better so unplugged it and started over. Second time it went all the way through but then the truck wouldn't start. I told him to put the truck back to stock and see what it did from there but still wouldn't start. He put it back to stock, it pulled up two DTC's P268A fuel injector calibration and P2632 transfer pump relay control circuit. Do you have any suggestions?

Unhook the batteries and try reflashing. Had this happen to an LML at the track.
