If you were running an unmodified oem ecu, your OBD knock logs would show differently. So would before and after compression results. Its possible your g-Force ecu has a non-oem timing curve, which could allow you to run 18psi safely with 93 octane pump gas. Keep in mind not everyone has a gForce ecu, so running 18psi on pump gas is generally bad advice. Either way, best of luck.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
