Stuttering but doesn't show in logs.

Hi.
I'm having a hard time figuring out this problem here
where it feels like missfires but doesn't show (to me) anything in the logs.

I've had real missfires and clearly shows because of the lean spikes.

Using an msd and msd coil with plugs gapped to 0.025.

Thanks for looking. All opinions welcomed.
4th gear pull on the freeway and have to let off just when it starts to get good.

My car misfires in that area too. I think it may be caused by knock, but I am not sure. Try adjusting the timing either way to see if it lessens in that area. I can see the misfire, its happening directly before the blue line. You can see it in the RPM and AFR.

I'm retarded.
Just to close this thread it turned out the plugs were gapped at 0.030.
Guess even msd couldn't jump the gap. Gapped them to 0.025. Everything is good.
Knew it was going to be something stupid. Thanks for the help.
