Disappointing dyno results 370z 7at

Jordo!

OP (and everybody else):

Provided you use the same dyno, whatever kind it is, and use the same correction factor, and dyno in the same gear (again, 4th is fine -- less stress on the motor), you can always determine magnitude of gains or losses by the percent of change from your baseline (of course, that means you need a baseline...).

In other words, absolute values are less meaningful than the delta (i.e., a gain of "5 whp" isn't as clear as a gain of "3% from baseline"). Likewise, don't dismiss gains under the curve over peak gains.

A good way to evaluate overall change is to look at the % change where hp and tq cross (i.e., 5252 RPM).

Peak values are only critical for drag racing time and and top speed, but for daily driving and your "butt dyno", you will be more aware of changes much lower in the powerband, and off the line most of all.
