only 304rwhp @ 17psi guys. something has got to be wrong. a/f's were good, vf is good. I did however find out that my egt probe had backed out of the exh. housing on the turbo but that still wouldnt make that big of a difference. This was also on a Dyno Dynamics which is usually known for reading lower numbers.

I remember the af's though. It was super rich (10.2) at 3600 rpm and by 3800 it was steady at 11.2 to 11.4 the rest of the rpm chart. The boost was bleeding off from 17psi @ 3600rpm to 15 psi @ 5500rpm. which I think was partly due to the egt probe leaking exhaust (in the turbo exh. housing).
Last run we got the 3600 range leaned out to around 11

11.2-11.4 really isnt that bad.

id do a compression check to make sure everything is good there.

maybe it was pulling timing?

it was a new build. ran great (first 1000 miles) until after the first 3hrs on the dyno with too much fuel pressure.
