So yeah, my question is does lower final drive affect power read outs on the dyno. From my understanding FD is kind of a torque multiplier, so does this affect the power reading or not?

For Example.

Same CAR

Run on Dyno with EK4 box - 4.4 FD
vs
Run on Dyno with EK4 box - 4.9 FD

Would the power figures change?
