I do not doubt you would pull 180's on a Dynojet. 171 on a Mustang is really high from what I have seen over the years.

All I stated was adding XX% to your recent dyno numbers might give a general guesstimate of what you would have pulled on a dynojet but is not the same thing nor "exact"

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
