I recently installed the SS AFC with datalogging and I have had a huge problem with it running lean. No matter what map I use it runs way to lean. AFRs on boost start at 11.5 and creep to 15 before I either pull back or it cuts. I am running stock boost pressure. relocated MAF, FMIC, forged internals, stock downpipe and j pipe but with a 3in true straight pipe (pope DP coming soon) Its like the afc is having the opposite affect that I need. Any info will be great. And I might need to play with the settings a little but its almost as if the afc has made everything worse. But for now I have only downloaded maps from the library.
