whatever holley has them set at. it isnt tune related if thats what your getting at. its been looked over by a few highly respected tuners. we know its electrical cuz it has made clean hits but very inconsistantly. holley sent me a complete main harness for free under warranty 10yrs after purchase date. that tells me they had issues with them and knew it. 2 other ge holley guys ive talked to had harness issues and similar or nearly identical troubles as me. the harness fixed it to never see it again. so im counting on this to be the same. as my harness was a very very early setup up when g3 first became available.
