My truck started to regen every 125-200 miles and I noticed a small amount of black soot inside the exhaust tip. Dealer told me the aftermarket CAI was causing the problem "more air equals more fuel". This does not make sense to me. Any help would be appreciated.

How many miles on the truck? Is there any smoke out of the tail pipe when you rev it in park? Like foot to the floor and then off throttle, don’t roll into it

You probably have an injector problem, you need to scan it for codes and look at injector data. If you keep driving like that the DPF will pull up.
