Hey all after much time spent searching here and several different internet sources, my mind is spinning. I'll start with my truck, 20g/14cm, built trans and 3K stall, 340FP, 75# injectors, MSD coil, and just switched to e85. A tune up is up next and wanted to get a clearer idea of what gap to set. Currently running a UR6 set at .30-.32. I'm hitting 21 PSI now, and there's still some fine tuning left to do so not really sure on AFR on the WB just yet. The info here shows lots of stuff from super tight .15-.18 up to factory setting of .35. Some mention Meth, didn't really see any e85 info. As always any advice is appreciated.
