Under Pressure Performance uses a DynoJet 248 chassis dyno for all its diagnostic and performance tuning. The dyno hardware and software is updated as soon as an update becomes available.

All of our engine/driveline research & development takes place on this chassis dyno.

We can test and tune vehicles up to 1800 horsepower at driveline speeds up to 200 miles per hour safely, consistently, and reliably.

Of course it is equipped with a wideband O2 sensor (which is changed regularly to assure precise air fuel ratio monitoring), boost pressure logging, and load control.

Dyno tuning allows us to:

• Quickly and accurately diagnose problems
• Test/Verify performance gains/losses from items such as cams, turbochargers, exhaust systems, boost devices, and other bolt on modifications
• Fine tune vehicles using measurements from diagnostic devices such as Air/Fuel ratio sensor(s), manifold vacuum/boost pressure, EGT’s (exhaust gas temperatures), and RPM
