2007 2500 TRX 4wd,6.7ltr 138k miles, noticed that when driving under light excelleration I have black smoke out of exhaust. Have muffler, but no Cat or ex parti filter, delete kit installed, min hp gain. Engine feels like lost power. And now the coal roll. Only think that has been worked on lately, is AC compressor, and cond coil, accumulate/filter, hoses, belts, pullies, belt, expansion tube, changed, don't think this has anything to do with it. Any one have this issue? No codes. Any suggestions on what to check, or what could have gone bad. It is like running rich. BANKS AIR filter is clean,. What would you suggest I check
