Tuning For Detonation

Aight den. We just got back from town. ZERO detonation there. ZERO detonation luggin hell out of it around town. ZERO detonation on the way back. The temp now runs about 1/8 the way up on the gauge. I have to wonder if even the 180 thermostat was opening all the way. I know from the IR gun evidence the 195 was not opening at all. @yellow rose, here's you a plug picture. Sorry for the crappy focus. I'm not really good at readin um and I know you really should cut the shell off....but I ain't doin that to new plugs. lol Also the second picture is close to where the temp gauge is drivin it. It actually runs more to the left of where it is....about 1/8 the way off the cold line.
