I installed XR, and went to run some logs.........
And now I keep getting "negative pressure deviation" DTC's. Do I not want to use the TCD with the XR chip??? The MBC is set the same as with the X.

I want to see how the TCD setting and the requested look.
Maybe the requested spike on XR is higher than X, resulting in a negative deviation code due to the much lower actual? It could be a number of things, but it's all speculation until we can see it. If you want to get experimental, try reduced SEL scaling to 95% or so and see if it disappears.

I forgot you are not full stage 3, just 3-.
In that case, SEL is the best route. The reason I didn't say that as your first option, for some reason thinking you had full stage 3 homebrew, was that reducing SEL while running MBC in parallel will cause you to taper more up high.
