I would bring Ltrims down with translator, but be prepared to lean WOT settings down to make good power, been there done that. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

You want to have slightly negative LTrim in cells 1-15. Your WOT O2's will vary. I tuned mine for .890 and when I dyno'ed, it indicated an A/F of 13.5 from 3500 to 5500, then went to 13.0 from 5500 to 6500. This, obviously, was too lean and resulted in a 1st pull of 383.9 rwhp and 367.5 tq. For the next pull, I fattened up the PE/RPM table 5% and got my A/F down to a flat 12.5 accross the board. The result was 387 rwhp and 369.5 tq. Autotap on the way home showed my WOT O2's were in the .920 range. Each car will be different.
