I'm working on a 99 5.3 with a chinese 2 stage cam. It was extremely rich and I got the MAF calibration done. Runs ok MAF only just start up can be a little rough. My question is in speed density I set up my graph, note I'm using narrowbands but I'm only idle and cruising no WOT or getting into PE, but no matter what I do to my VE table I'm still rich by -8 to -14. And I've made some pretty drastic changes to this table. My DFCO is off MAF failed SES light on first error. I've knocked up to about 35%-40% off my VE table from 400 to 1200 RPM and still this rich. What am I doing wrong or missing?
