I have a Maggy Blower on my 5.3L Silverado, the canned tune that came with it has the commanded AFR set to 14.17301. I am going to switch to the 2BARSD OS any reason to keep it at 14.1? I understand you want to be richer with boost, but Stoich can still be 14.7 right? Also, with only 6psi what should i be wanting in boost...11.8 good or closer to 11. Have read all the help files and know how to change everything, just wondering if anyone has run this setup and knows what it likes for AFR.
