JSBENZ gives all the ECU’s a rigorous testing, on both the street and dyno. That gives you more power, sharper throttle response, and a complete focus on the driver makes this the perfect addition to your vehicle for a much more enjoyable experience for you.


  • Eliminated Top Speed Limiter
  • Improved Throttle Response
  • Optimized Fuel, Spark, and Boost

DynoJet AWD – Dyno Tuning and Rental

At JSBENZ we offer our Dynojet 424x model. It features a precision balanced drums and measures up to 2000hp, 2000 ft/lbs, and 200 mph. Unlike inferior non adjustable wheelbase designs, the model 424x can adjust wheelbase with a push of a button from 88” to 140”.

This allows the tires to contact the rollers evenly and in conjunction with the large drum diameter the 424x provides a virtually flat, stable surface for tire contact, eliminating unnecessary tire slippage and deformation. The result is precise, repeatable data every time.

When increasing your Vehicles Performance your ride will need to be tuned so that your products are functioning properly. Your build is only as good as the tune moving it! All Dyno Tuning is done on our in-house 4WD DynoJet.
