my car has some light pinging at WOT at higher rpm's N/A and when spraying, its about the same amount so i dont want to say that its the nitrous. shouldn't my car pull timing by its self.......i run premium all the time and have tr-6 plugs. is the knock sensor messed up? help!!!!???!?!?!?!?

Have you verified your AFR with a wideband or at least scanned the O2 sensors to check AFR?

no i have not, but i am looking to tune it in the near future....would this be my best bet.

Well you could be leaning out which would be a cause for knock. First thing is to check AFR. Maybe first make sure you have a clean fuel filter.

if that checks out, check your knock sensors. even the new updated sensors (late 98+) still has issues sending false knock during WOT high RPM pulls if they get wet. if you find they are (or have been) wet, replace them and take some silicone and build up sort of a dam around the sensor holes to protect them from moisture.
