Mine was running rich too w/ similar mods. Plus the knock sensor kicked in about 4200 rpm, when i looked like I was heading to the 320hp/340tq range. Tech speculated that the plugs were just too hot, but it was rich too, so I don't know. Was still pretty happy w/ the #'s. It was done before the descreening and the FRA by the way. Nice numbers on yours!

 

My knock retard kicked in too at around 4600 rpm since the numbers on the graph dipped down slightly in both hp and torque. My A/F at 4k was way rich at 11 then came backup to 11.5 at 4700 and stayed there. I tried scanning my dyno sheet but the whole graph won't scan. The rpm's and A/F graph don't show up? I thought about calling up SLP and seeing if I could get another mass air since mine isn't leaning the car out at all then again it could make me run to lean and that's bad.
