Hi. I tuned my Audi, but i dont now how much power and NM it has now because there arent any 4x4 dyno near my location. I attach VCDS logs:

how did you figure out the power of your car with out dyno it?

580nm - maybe, but 295hp - no. 260-270 maybe.

Max power at 4000 rpm.
Torque at 4000 rpm = Iq 73 * nr of cyl 6 *6/4 *correction factor (For 6 cyl. engine the factor starts from 0.9 and folds to 0.8 at high rpm)*0,8 = 525 Nm
Power = torque 525,6 * rpm 4000 /7121 = 295 bph

That's a good estimate, but only represents the "optimal" values in an ideal world. In reality the engine has external losses before power goes on to the drivetrain, which are not present in the ECU.
