I have a brand new 2018 Silverado on the dyno. We just installed a P1 Procharger, truck is otherwise stock. The timing isn't staying where I want to be WOT and I've been chasing down the reason. While doing this I tried changing B5157 and it had no effect at all on my final timing. This has always worked in the past on other platforms, has anyone else seen this? I'll attach the stock tune
