Shawn, Funny story regarding todays dyno and my low numbers (405 at wheel). You may or may not recall last year after my first pull you suggested removing my floor mats. The numbers went from 407 on that first pull to 433 and 435 on the next two. Guess what I forgot to do this year . . . yup, remove my 1" thick floor mats. The F/A mix from last years run were almost identical to this years so I don't think it was the "rich" issue. Not sure if the floormat is the answer but last years' first pull at 407 is awfull close to this years 3 pulls at 401, 403 qnd 405. Mike
