My clip came w/ a veilside tuned ECU. I compenstaed for everything so far that it may be tuned for except for the gas. I assume the ECU was tuned for max power from high grade japanese pump gas, whatever octane that may be. All I know that is probably better gas than I can get from the pump here. So what I need to know is how much I should retard the timing so I can use 93 octane and not blow my engine up. Any info or suggestions are appreciated. Thanks.
