Awesome numbers. The BB campaign does a great job on those engines.
A set of 130 mains & stock needles and pilots may be just the ticket to clear up the popping
without going too far into running rich. That way the fine tuning aspect can be shifted to the
more incremental method of shimming the needles. You might even get an extra HP or two.
From your signature data and dyno chart I would believe it's just a hair lean right now.
I could be wrong.
