Smoke generators are used for emission system testing, the PCM is great at compensating for most of the mods that are done. But to actually know your Air/Fuel (A/F) ratio and to tune you will need to install a Wideband A/F gauge. There are many out there and this is only an example. http://www.summitracing.com/parts/inn-3795
We have excellent venders on the forum. I choose to show Summit because I can show the product I am referring to and not just a home page. To check for exhaust leaks you need to get under the vehicle and check manifold and exhaust joints back to the mufflers. New cats and mufflers often will make tinkling/popping noises during the first few heat cycles. I'm not sure what you are describing, maybe just the rumble/popping of a very open exhaust on deceleration?? There are many different methods of tuning from stand alones to various forms of piggybacks. The most favored custom tunes among the Ram folks are the Diablo CMR, SCT and PCM reflashes. I use a combination of SuperChip "Canned" tune and a PSC1 piggyback inconjunction with a High Idle Mod and will be trying a stand alone tuner in parallel with the OEM PCM shortly. I recommend going slow focusing on one mod at a time, sorting everything out as you move forward toward an established goal for your truck. Good luck, plenty of folks here to help you.
