Misfire at WOT 2014 s/c c7

[hnaskoct]

I have a 2014 c7 with procharger 9-9.5lbs,headers, and 100% meth..The problem that has happened a few times is that at some point WOT the engine lights starts flashing indicating there a misfire but the car isn't missing of any sort..it blinks about 15 times then goes off..doesnt happen all the time but sometimes as I'm racing it happens and I immediately let off throttle.I finally got my lambda dialed in around .82 but that still didn't stop this prob..heres my file and datalog what do u guys see ..im learning this tuning stuff day by day reading, reading and listening from all u pros out there lol.

Not sure what your plugs are gapped at but is it possible its blowing out the spark?

ngk iridium ltr7ix-11
gapped @45

[rbooth]

.045 is too much for boost. I would put them around .030 and I think your problem will go away

[Ben Charles]

I would close that spark gap as well

[hnaskoct]

ok thanks guys ..does the log look decent?

[yonson]

Log looks fine, close that gap to .028 - .032 and you should be good to go...

Was you able to solve the issue, I notice that you car is reading up to 5 degrees of knock retard and the car is programmed for 15 degrees on that region. It seems that you may be running around 10 degrees of total advance. I wondering if the rootcause for the knock retard are the spark?

that is a huge gap for sure
