![]() ![]() Driving the car under all circumstances, like coming to a stop, making a hard left/right hand turn, loading the engine, all this is necessary to collect data, which then can be reviewed and changed accurately. You need to see what the engine is doing in order to adjust it correctly, otherwise it is just a guess. In our opinion you can’t get the tune correct with just the dyno, the car has to be tuned on the street as well. We use the dyno for wide open throttle tuning and do all the drivability stuff on the street. The dyno tune also includes the tuning on the street. ![]() From there we are able to adjust the tune for horsepower and torque and find the perfect fueling and timing for each vehicle. A wideband allows us to see the exact air fuel ratio form the vehicle and make sure fueling is tuned correctly. That is unless the car has widebands from the factory, like a Coyote or Hellcat. A dyno tune here at DBR consists of not only a street tune but also us setting the car on our mainline hub dyno and installing a wideband into the exhaust system. ![]()
