Default tuning issues

This is what my tuner is saying

Okay, at 5 or so PSI I am making 418/408 and a lot of KR with me at just 12 degrees of timing.
It could be false know due to the exhaust dumping where it is or a rattle. But with a boosted car I hate to turn off the knock sensors in case it is real.
I can try turning them off if you want, but if you say okay and something happens I am not to be held responsible.

Any thoughts what issues could be?
Car 98z on3 non ac 76mm kit tick stage 1 cam with 317 heads 60lb injectors single walbro. Plugs gapped to .30 running 7lb wastegate spring
Any help asap is appreciated!

98's have serious false knock issues, I would turn them off as you should rely on them to save an engine.

Maybe tighten up those plugs. Are you using 1 step at least colder plugs? What air fuel is it at when it is knocking?

Might put some race gas or Torco in it just to be safe while learning what the setup likes!

Pull a plug and read it, only real way to know what's going on.

I had this problem before I had to buy 2 new knock sensors from GM to fix it. I had tried 2 from the parts store and they were junk and continued to show knock no matter what. Bought one sensor from gm and it took care of the #1 side then replaced the other and boom knock free.

My car was an 01 z06 with a 402 solid mounts and a 88mm turbo. I fought with the issue forever.
