:cool:If the final On-road tuning and test-driving already being done perfectly, then what for still hook up to dyno to re-adjust the tuning with the dyno's power simulation error? Make it simple- The dyno is just a power simulator which equipped with simulated power load sensors and do not expect 100% accuracy.
:cool:No matter how good is the Ferrari or Lambo's racing dyno equipped, they still need road tester like :- Mr. Micheal Shoemaker, Mr. Alonso & etc.
