Hesitation at WOT

[opzWE4]

I've got a hesitation at WOT and I'm not sure what is causing it. It pulls, but I can feel it kind of stuttering up top. Direct scan looks good and I have no knock retard. I'm running 19# of boost with a mix of 93 and 110, on a Reds 93 Street chip. Again, no knock, and the boost doesn't fluctuate, it stays steady at 19#s. Any Idea what might be causing this? O2's are in the 780 range at WOT in third.

Sounds like Ign. problem , coil pack could be weak, plugs and wires may be weak , gap the plugs @.032 use a cold plug like autolite 24 or 23
This is not an uncommom problem

Thanks Mark, I'll try some new plug wires and maybe plugs, although they aren't that old. May need to check the plug gap again.

Sounds like a coil pack to me too. You can check your wires with an ohm meter. Obviously the longer the wire the more the resistance but they all should be in the ballpark. If you have one that is way higher than the rest then it may just be a wire.
