The power of stock coils should be just fine for him. You and I are both running stock coils and we have a lot more power. My MSDs were fine up to a 3.1" pulley. He should test them. His plugs are what I'm thinking. To hot and they will stutter. I suggest autolite 104. If he was running lean, he would have knock. If he was running pig rich, it would seem sluggish and show up on his LTFT. I think he has 10.5mm ZZP wires. These have also been shown to be less then reliable.

I've got autolite 103'* gapped to .55 if I remember correctly. I think I need to jump those back up to 104'*, that would be a good time to re-gap and see how that goes.
Brand new factory coils because my second pair of MSD'* were studdering bad.
Sounds like maybe I should test the resistance on my wires as well. You have MSD wires don't you Dan? How have those been working out for you?
We did VE first. Never got to the MAF on mine, had to stop for the week.

Yes, I have MSD wires, no problems. MSD coils seem to be good on a stock or lightly modded car, but once air flow goes up, they tend to have a weaker spark. A tighter gap may help, but that'* not fixing the underlying problem of a weak spark. The 103s may be a bit cold for you yet. I'm running 103s and have a lot more boost. I say go to 104s and gap at .050 and see if that helps. Check your wires. You didn't say if you have ZZP wires or not. But I've seen several people complain about loose connections. Pull your plugs and inspect them One thing I'm sure you have not done yet is skew your injectors. The front bank tends to run a little lean if I remember right. I'll have to pull up my tune to give you an example.
I think I found it.

I do have ZZP wires. I'll jump back up to 104'* and try a .5 gap. My injectors were already skewed because I had a ZZP off the shelf tune. They did it differently though. Instead of raising 1, 3, 5, I think they left them at 1 and lowered 2, 4 ,6. to below 1. Does it make a difference either way?

If it is darker, would that signify a rich or a lean condition? Rich meaning I lower the skew, lean I up the skew? I should get my car back for good this weekend so I can get all of this done.
