Last month i dynoed with ls1 edit a/f was 13 at wot , went back today lost 20 hp a/f was 11.6 -11.8 weather was pretty much the same

horist

maybe when it was tuned the LTRIMs weren't zeroed out... normal driving forced the LTRIMS to go positive, causing added fuel , causing LTRIMS to lock at a value great han 0 at WOT which would add fuel at WOT and cause the AFR to go rich...
