    i am getting detenation, when im about to get into boost.. 0 vaccum.. line.. timing is at 16.. i pulled the plugs to inspect and all plugs except one doesnt have a knick on them electrodes... like the piston is hitting the plugs electrodes and causing lil knicks off the electrodes.. i got the A/F at 11.2-11.4 right before it detnated and truck ran crap.. does that mean the timing is high or to cold of a plug or what..???? i am using NGK BR7's gapped at .36

    You most likely have bad gas. It may also depend upon how many miles the plugs have on them. Under harder usage they should be changed at 10-15K. 16* isn't too high, I ran that for two years, you could back it down to 14* to be more safe. I had the same issue last summer and I pulled timing until I could change the plugs. IDK if it was the plugs or bad gas but it was cured.

    Sounds like you got bad gas, if so changing the plugs won't help. Pull at least 2* global timing out until the gas is gone. Gapping to .032" is too close unless you're running 20+ psi of boost all the time. 16# and less boost gap them to .036".

    Bad gas = lower octane or maybe some water in there. Would cause det.
