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!

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.

hey ghost-1 was your car a 98? and i understand that reading a plug is the only real way to see what is happening. i picked the car up yesterday and will be pulling plugs this weekend.
My car was an 01 z06 with a 402 solid mounts and a 88mm turbo. I fought with the issue forever.
