86 LG4 to SD TPI base timing ?
My LG4 sticker under the hood says to set the base timing to 0°. I'm installing SD TPI setup with an AXXB PROM. Should the timing still be set to 0°? Has to pass the emissions stiffer test at idle and at 33mph on the rollers. Thanks

If your installing TPI then the timing should be 6 degrees before TDC.
