Default Anyone tell me what's up with my A/F reading?

Wondering if anyone here can tell me what's up with my car running rich in the top-end. I was told in the dynometer forum that it might be my spark plugs, but I'd like to know if anyone else has a suggestion on what it might be? Either way, I think my could would do good to get a tune.

Thanks!

(edit) Oh and by the way, when I was on the dyno the conditions were not exactly the best, as it was raining outside, and my tires are bald bald bald . First two runs were only 285 rwhp, so me and my bud hopped in the back of the hatch (added ~400lbs over the rear wheels) and gained 12 rwhp.
