down here at the shop... we offer an ignition add-on that will retard
the knocking cylinder and let any others that can handle lead run with
it. On a 96 Indy ram w/4.11, SBEC, 1.7s, FIPK, our TBI, & our MSD/MPI
kit... that runs 9.60 in 1/8th and pings all too often and all too
much... it 100%, totally cured all and any detonation. The owner came
by tonite and was in hog-heaven... nuff said...step up and try good gas
often to keep injectors as clean as possible...I run only 92 in all my
efi type vehicles... 87 may be a few cents cheaper... but not in the
long run...
