Problems on the dyno

I have had my 2009 135i Automatic dynoed at two different shops in the last two weeks and showed really crappy numbers. While running Map 6 (Custom Tune) 15 lbs of boost with a DCI I ran 308 rwhp and 310 lbs/ft. I then ran VP 104 on Map 7 (Race Tune) and ran a 322 rwh and 332 lbs/ft. I know I should around 355-380 rwhp. I spoke with the tech at Dallas Mustang and he said that my Air/Fuel Ratio was high. I was running too rich. My AFR was 14.8. Any thoughts?
