Optimizing A/F & Spark for WOT 404 hci?
But, I want to know if anyone has some suggestions for maybe trying some different spark and a/f combinations.
I have a 404 ls2, ported l92s (11.5 CR), 240s/250s cam 114+3, and all the supporting mods.
Right now I am using 12.5 a/f and spark that goes from 26* to 28* at WOT, it pulls like a raped ape, but I wonder if I should try other combinations?
Does anyone have any experience with similar setups and know what works and what doesn't?
