What do you guys think about putting the ACDelco 41-128’s in?
I have exhausted all my options on my Procharged ‘19.
With the stock SS plugs ACDelco 41-103 (I think) i was getting spark knock at like 5k at WOT in 4 gear and up.

So I changed over to the ltr7’s and i’m getting a massive amount of misfires. It starts cutting out at the top of a gear when WOT when doing a roll.
I had them gapped at .025, then gapped them to .040 per JRE recommendations and i just cannot get rid of the misfires.

So i just ordered some ACDelco 41-128’s which go in the ZL1’s and i’m leaving them at the stock .030 gap.
