I'm hitting 10.0afr wot on my wideband, I have a sz eprom, and was told that I should be hitting low 11's if everything is correct. the only way I can hit 11's is if I dial down fuel pressure to where its 32 at idle with vacuum connected, which seems to be the sweet spot. I've went through my entire intake and intercooler piping and repositioned and tightened every clamp, timing is 15', fuel pressure is set at 43.5 with vacuum disconnected. I have a walbro 485 direct wired, and a tomei large diaphraghm fuel regulator, with 740cc injectors. I've went through the 6 steps, and just don't know where to go from here. its a dual oem maf intake system with the selin, the chip is for 93octane, 740cc injectors, and single intake so I have the selin to add, if anyone has any ideas let me know!
