Cause to be concerned? Some black smoke after changes.

105,000 miles. 2006.

I was running the GDE full-torque eco tune prior with no noticeable smoke. I recently got an engine light telling me that I had a bad glow plug. I upgraded to the new 5 volt system glow plugs, and while doing that I cleaned the map sensor, upgraded to the GDE hot tune, cleaned out the intake pipe of gunk (assuming it developed from before I had the first eco-tune approx 40k miles ago). Now, engine light is off (I cleared it with the computer I got from GDE), jeep runs great, but I am getting some black smoke under hard acceleration. Is this just cleaning crap out or what else might it be?

Thanks!

I think at 100K our cats quit working, just a thought?

Some smoke with the hot tune is normal at full throttle.

bebey - unrelated to smoke but a reminder it's timing belt time if you have not already done it.
