Hp lost
 

Hi. My Boxster 2.5 on Dyno only have 187hp at clutch (160~ at wheels). I dont understand it because i have a 996 3.4 TB, hi flow headers and a kind of Technotorque inside plenum. Both bosch lambda new, verified TPS voltage and try a partner MAF with same results.
Anybody see anything strange in this log?

Can you post the dyno horsepower and torque graph with A/F ratios? That would be helpful.

I dont have it. I saw when tuner try to tune ecu.

Dyno shouldn't be used for stright HP numbers.

Only before/after comparison ON THE SAME DYNO.

I know, but I have seen other Boxster and get 204hp in dynamometer ... with the improvements should have surpassed them not worsened .... do you know the maximum flow rate of air that should get? 553kg /h is correct or insufficient? Thank you!!
