Company BrochureDyno Info


We tune multiple platforms on most all stand-alone EFI’s and OEM domestic vehicles. We use a Mainline DynoLog 2500hp hub dyno and lab grade widebands to make sure the data we are getting is as accurate as possible.

Our professionals know how to handle a wide range of car services. Whether you drive a passenger car or medium sized truck or SUV, our team strives to ensure that your vehicle will be performing at its best.

  • Street tune vs dyno tune… Which is better and Which do I need?

    One of the most often asked questions is, “What is the difference between a street tune and a dyno tune, and which tune is the best for me?” This really depends on the vehicle, the vehicle mods and your personal goals. A lot of times the vehicle might not need a dyno tune but the customer wants to get a good baseline before starting other mods. These are questions you will need to ask when deciding which tune is best for you, and we can help you decide.

  • Street Tune?

    A street tune consists of tuning the vehicle on the street, just like it sounds. Here at DBR we offer a street tune for vehicles that are mildly modified, like CAI or headers or even an LS swapped vehicle. We feel if the engine is basically stock spending the extra money for the dyno tune just isn’t worth it. The street tune still gets all the basic changes the dyno tune does; it just doesn’t get dialed in on the dyno with a wideband. We pull the stock file off, modify it, and then drive the vehicle and get a datalog. With the datalog we can then make changes to make sure everything is happy and working together as it should. All street tunes are custom tunes for each vehicle, they are not a “cookie cutter” tune that every vehicle gets.

  • Dyno Tune?

    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. That is unless the car has widebands from the factory, like a Coyote or Hellcat. A wideband allows us to see the exact air fuel ratio form the vehicle and make sure fueling is tuned correctly. From there we are able to adjust the tune for horsepower and torque and find the perfect fueling and timing for each vehicle. The dyno tune also includes the tuning on the street. We use the dyno for wide open throttle tuning and do all the drivability stuff on the street. 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. A tune is really all about the data. You need to see what the engine is doing in order to adjust it correctly, otherwise it is just a guess. 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.
