I put a new VF43 on last night. I primed it this morning and took it out for a drive. On the first pull there was a ton of smoke, but after that, pretty much none. My guess is that it was all residual and probably clogged/burned off from the cat in my downpipe.
Checking with my tuner now to see if it requires any changes. I'll keep an eye on the oil level as well.
