Hello I need help figuring out why my knock guage goes off at about 80 % throttle. I run 42psi of fuel pressure at idle with vaccum connected, and my VDO boost guage only reads 13 PSI. All the major mods that I have are in my sig. I run Mobil super+ 93 octane gas. The injectors are 42 1/2 pound.
Thanks for any help,
