I was woundering what you think. My detonation started after my tune up where if fixed my boost leak and swapped in the suggested UR6IX #7348 plugs. I have read thet some poeple say ONLY to use the AC Delco CR42TS. Who is right and could this be my problem?

If you fixed a boost leak you're probably running enough boost now to get into some detonation. I'm running the 7348's and I don't think that's your problem.

You need to know
a) how much boost you're running
b) what your gas quality is
c) how much timing you're running
d) what your AFR's are

Best thing to do is to get Datamaster and start looking at these things.... is really the only way to start getting a handle on it.
