I had heard a post awhile back from when some contacted MSD about the same
problem you are speaking of. They said that it could be the stock computer
is causing the air/fuel mixture to run a little lean and could be corrected
by increasing fuel pressure or with an aftermarket computer. At least I
think that's what the response was, anyone care to comment?
