Looks kind of like my dyno "curves" when I had a bad head gasket- check compression lately at 300+K?
I did no porting when I swapped the turbos. I'm thinking I will soon because my manifold has developed a small crack.
I checked compression around the time the first curve was made. Cyl #3 was a little weaker than the rest but still within spec. Other three were great. The car now has 311k and hasn't been beat on daily so I think compression should still be good.
