I've been Mustang-ed! Dyno input

Visited a great shop today...FFTec in Hayward, CA. I needed to do a baseline to get my afr rates after fuel pumps were changed out. Anyway the cars best pull was 397whp with 374tq. Question....for those that may have used a mustang Dyno before....are these ok numbers? If we use 12% correction to dynojet I may be at around 440-445hp?

I am running an Oetuning tune, shorty renntech header into primary cat, hi flow secondary cat into ipe exhaust. Drop in filter with row boxes.

Thoughts?

I can't comment on your numbers but I can conclusively state that running with primary cats in place puts you down 19 RWHP vs. the same setup w/o cats.

Yup I agree....just not worth the fumes and emission problems I could run into...removed my ipe long tube headers a while back and settled for this set up. Loss a lot of top end power for sure.

I use mustang dyno. From what is said yes reads lower than a dynojet but percentage is not known 12% is a guess. Stock baseline I put 390 rwhp torque don't remember.

Got it..I've been collecting some figures and so far we have a baseline p31 anywhere between 350rwhp-370rwhp and now 390rwhp on yours.
