This forum and community are great. I've never heard of carbon tracking before. Glad to learn something new. I take it this is something only prevalent with improved ignition systems and not generally common in oem situations?

No its can happened anywhere there is a spark gap to be jumped.. I'd have to say in my experience it is not as common with COP set ups though
Update:
Changed all gaps to .022"
Regreased
5 pulls all perfect. Making 30psi. Feels amazing just like it did when I first got the kit.

Glad it's working finally. Just sucks since you probably using the same gap you did before.
Yeah, I had the same issue. Was gapped at .025 and was getting a slight misfire soon as I went into full boost ( pure stg 2 HiFlow ). Re-gapped to .022 and been solid since! Glad you got it figured out 
my working great gap .22 no misfire running 26psi on big twins. just pulled plugs after 8000 miles they look like new, these coils are awesome. but got to make sure there push all way in. run ngk 1 step cooler plug
95770 are 1 step colder
97506 are 2 step colder
The coils make 44kV thereabouts, around 10kV more than factory. They make nearly 4x the energy though, which means if they span the gap they will fire hot with good duration. Calculate the gap of OEM and PR yourself at the bottom of this link. Add about 40kpa to whatever you calculate and remember you need a little buffer between max just in case. http://www.megamanual.com/seq/coils.htm

So how come people cant gap wider without issue ? Fueling issue causing misfires and people assume its just the wider gap ???
Any personal preference on the Audi coils vs these ? Also, why would you choose one over the other. Thanks in advance as Im looking to make a purchase but on the fence of which route to take.
