It's running too clean

I've had a few issues come up since getting the car back on the road. I've put about 1500 miles on. The one that I can't figure out is that the exhaust is very clean. I can go WOT and see no smoke in the rearview. I've been driving this car for 15 years and always could roll a little coal.

When I first got it back on the road it went into limp mode on 3 trips, but has not done that since. Power feels about where it should be. Not sure where to start looking or to just ignore this.

Maybe it is finally running correctly.

Exhaust took a small hit in the accident - I see a couple dents - maybe something was freed up?
Now I've got no way to back off tailgaters though.

I wouldn’t be concerned- I had a intake hose split- it smoked so bad I got 3 letters complaining about it from the DMV. I fixed the hoses, cleaned out the intake manifold and ports, all the tubes and hoses and replaced all the dodgy old vacuum lines. It blew 0 ppm, when I got it smogged (a yearly Colorado diesel annoyance). The guy told me the only way it would test ‘cleaner’, is if I had it turned off.

No- I am in the Boulder area, and drive into Denver and Aurora, frequently. I think it upset the Subaru drivers/bicycle riders. Possibly the coal-roller truck guys, too.
