Definitely seems like it's a spark issue. New plugs, gapped .17, and boost at around ~25psi, added a tiny bit of fuel from about 3k-5.5k and here's the log. Later in the day car seemed like it was running ok, but this log is just odd. No explanation for the weird dip in RPM. Easiest way to see the run is look where the MPH jumps up at launch. Also, tried to log the o2. Tried front first, got a constant value of 7.4? Then the rear, and the values changed, but seemed weird, you guys can take look at the log. The in car gauge didn't go above (leaner) 12.6:1 during the run, and that was with the weird stutter. So... coils? Timing off? Again, was smoothing out a bit later, but still not 100%
