Check the two new hoses between charged air cooler and turbo. I’ve seen two instances where mice chew small holes in hoses on the side not easily visible until removed.
One was in the barn in off season the other was in the field overnight.
If it didn’t black smoke during beans then I’d figure your repair was good. Slip timing usually occurs on hot rod throttle operation and a combine doesn’t really fit that scenario.
