[Spoolindiesel]

Hey guys 2003 lb7 5" Exhaust edge cs tuner cold air kit
I've been noticing a bit of fuel knock
Starts good no issue number 6 is sitting at 7.0 and goes as high as 10.0 after a hard run
On cold start stays around 6.0 to 5.9
On the edge cs injector paulse

So just did the Walmart 2 stroke oil injector balance before where 9.0 to11.0 on number 6 injector now reading 4.5 hmmm noise seems to be getting better
I think I'm going to put a yellow rollback happy face on my truck lol

You might want to do a fuel injector clearing.
