Weird Load # at WOT & Stuttering
I'm getting stuttering/hesitation at about 3900 RPM under WOT. It's right around 29psi and up to 32psi that it does this. According to the logging it looks like I'm at 350 load then it goes down to 5 or 1 load. Is this because I may be getting to 360 load and my maps only go up to 350?
I've already adjusted my fuel cut load to 638. It also may be my plugs (about 5k miles on copper plugs).

Lowered the timing by 2* last night. I'll lower more up top thanks to some sound advice from tscompusa.
I raised the 1 byte factor to 1.5 which does show the right load now (360). I'm still experiencing the stutter. I'm changing the plugs now. I'll test tonight. I use NGK BR7ES at .022" gap. I had these in for about 5k miles. The plugs look good/normal. I think I'll gap them to .020". I think 32 psi of boost is causing it to blow out the spark.

Is this on the stock coil dwell settings as well?
