Did you re-enable the MAF? If you AutoVE in SD and then re-enable the MAF with the stock MAF table, it'll be lean and you'll need to tune the values in the MAF table.

on this one i re-enabled the maf then maped it so i could auto tune it also

If you tuned the VE and the MAF, then it might be faulty O2's.
