Crazy amounts of knock.

[nfernotalon]

Hey guys I was trying to get my auto gsx to run decent on the stock turbo but it gets over 14degrees of knock anything over 4500rpm. Ive tried leaning it out, richening it up and makes no difference. Its at about 16psi of boost. It has 1200cc injectors aem 340 pump afpr. Link v3.

Is it just the tiny turbo that its at its limit? It is getting a bigger turbo and better manifold in a month.

Which spark plugs do you have? And, what is their gap? Also boost leaks ca contribute to this.

How old is your knock sensor

Could be heat soak if you're on the stock side mount.
