Tuning is an essential and often overlooked key to having a
well-rounded performance vehicle. Altered Atmosphere Motorsports,
Inc. is the proud owner of the United States' first All-Wheel
Drive Dynojet. Our experiences with this dynamometer, including
tuning over a thousand cars with it, has given us an unsurpassed expertise of motor vehicles in our industry.
what is a dynamometer?
It is a large testing instrument that simulates real world driving
conditions that allows us to properly tune cars safely and effectively.
The Dynamometer also allows us to test the performance of different
products, find out what parts work best on your vehicle, and
develop our AAM Spec. parts. To learn more, check out our Gear
Head 101 section.
getting it done
Altered Atmosphere Motorsports, Inc. has several options available
for the dynamometer to suit just about any project for your
front-wheel drive, rear-wheel drive, or all-wheel drive vehicle.
These options range from a basic two pull baseline to see how
much horsepower your vehicle is making, to an aftermarket tuning
session by one of our skilled engine management experts. To
schedule an appointment on our Dynojet Dynometer, please give the service

* Please note several vehicles, such as the Mitsubishi EVO and most Audi models, are considerably harder to strap down and prepare for the dyno session. These types of vehicles carry an additional $35.00 preperation charge. We have the right to limit the maximum dyno pulls to any one hour session. We do not allow more than 12 pulls in any one hour time period. This is not only abuses the dyno, it is abusive for your vehicle as well.
