that last log looks a little better. your avg ign is still in the threes though the entire pull.

Your boost target drops to 16psi at 5922 rpm for some reason, and then the next datapoint which is 2 seconds later actual boost drops, I am guessing because it is reacting to the lower target. What is weird is that next data point after 5922 rpm, which is two seconds later per the time stamp, says the rpm is 5892. How does RPM drop by 30 after two seconds? I just don't trust the JB4 to be honest. I know you are tired of hearing the same thing, but I cant help it. TWO seconds between logging points?!

I would pull the jb4, get the MHD logging capability, and see how she is running on stock boost. Or, if you can, load up the free ppk flash via winkfp that is on N54tech.
