I am haveing one HELL of a time getting my rockers set....when I first set them they were too tight I could not get over 17-18 psi and it had a bad miss..I reset them agin I think they are real close (hot lash) now the boost is up right BUT it has a diffrent miss at high psi (i.e. 20-22 psi) I have changed everything my EGT max was 1550 my question is if the rockers are too loose will it cause that miss??????
