Moin Am today with my V70 D5 Built. 2002 163Ps times faster. At 4500 rpm and 210 after Tacho was close. The car is equipped with the normal 5g Automatic transmission and winter tire 215/60-16 (approx.70%). The 4500 rpm has reached the car very quickly (Steinbauer P-Box) My question to other Automatic drivers or to all those who know. At what speed is the engine adjusted? Which speed can you reach with which tires at what speed? it around the pros or cons of a tuning box
