I have a 2002 GT with a JLT CAI magnaflow catbacks it has alittle over a
100K on it and i noticed when i get on it in 4th gear at about 2,000 rpm i get alittle ping sound and when i put my bama 87 tune on its really loud and it will do it with short stabs on the gas when the tune is on any ideas how to clear this up should i change the plugs as they are OEM from when the car was built should i run seafoam i need help fast

 

really need to hear the ping to diagnose a problem like this
