Question about my dyno results??

Hi all, I had my 2008 135i dyno'ed the other day on a Mustang dyno and I have 310whp and 349 lbs tq. I was hoping for more. I have a cobb stage 2 sport map, FMIC, catted downpipes, mid pipes, DCI? I had a max of 17psi boost. I was wondering how you guy's are getting 380 or 400 whp?? I think the Agressive stage 2 would only get me a couple more pounds of boost. I am running the stock muffler but I don't think that's very restrictive. My catted AR design downpipes seemed to be very free flowing? Where am I lacking?

P.S. The fella who dyno'ed my car said he did it in 3rd gear not 4th. How much difference would that make?

Thanks a bunch..

Your numbers do seem very low. Did you try running the new Stage 2+ that came out for Cobb? I put down 320/370 on a Mustang dyno as well. What shop in Rochester did you get dynoed at?

Mustang dyno gives out lower numbers compared to a dynojet.

A) mustang dyno
B) catted vs catless downpipes
C) conservative (and rightly so) OTS tune

what correction factor was used? what were the ambient conditions?

4th gear would probably give you even lower results than what you already have
