Hello friends. I've been racking my brain trying to figure out why my idle is so rich. Vehicle is 87 SL with +40's, tu fuel rail, AFPR, 3 bar, fmic, tu cast manifold, 50 trim. Everything else is stock, head cam etc. Fuel pressure is set to about 55 with the vac line unhooked. I have been messing with the tune but I'm kinda thinking it's not a tune issue. Any other ideas why it could be so rich? Right now I have a boost button stage 3 cal that has been scaled to +40's that I lowered the fuelbasedonmap table even further at 15-20inhg but it idles around 10:1-11:1. I'll get some pictures of what the fuel tables look like.
