Re: [ISTA] Bang at high boost - help!

Aaron,
my Sy does the "snap/crackle/pop" stuff when it goes lean under boost.
I suspect that a diacom might reveal some sub 500 O2 numbers while
this popping is present.  I'm betting that poor fuel delivery under boost
is your problem.  Have you connected a monitoring device?
