loping, surging or a missfire?

I hope to find a little help here, I have a 2010 2ss 6.2 6manual car, it has a dyno tune, CAI, ARH complete system, and a polished throttle body. almost 50,000 miles on it. Lately in the 1000 to 1500 rpm range while decelerating or holding that rpm range in the lower gears such as surface street speeds, the car has a surge, or a lope or a misfire. I changed the spark plugs, they all looked great, so I am confident they are not the problem. Any ideas or suggestions? thanks for any offered. Ron TIlley

Could be a bad plug wire.
