09 Impreza 2.5i MT


this has got to be the greatest dyno forum i have seen for a subaru. i just finished going through all 29 pages. i have a question for the NA owners or anyone familiar with the engine. im trying to find my peak torque and peak horsepower engine speeds. i have seen many NA dyno graphs and each suggest a different RPM.

for example this two from 06-07 2.5i suggest different RPMs?:

from an 08 impreza and 09 legacy also are conflicting:

can anyone explain? thanks.
