anyone ever tried lucas oil stabilizer? engine knocking

If your all stock then why did you raise the boost? I wouldnt rais the boost past stock ~11 psi until you rewire your fuel pump of get some fuel management. You will probably be hitting fuel cut soon if you raise the boost even more. I would lower the boost a couple PSI and see if that helps since your maxing your injectors already.

Could be carbon deposits on the pistons causing knock also creating hot spots...etc.
