You should also have the following gauges available to properly check the finished installation and monitor
your vehicle’s performance (especially for testing):
• Manifold Boost Pressure Gauge • Fuel Pressure Gauge • Wide Band Oxygen Sensor and Gauge
Gauges should be of a type that can be read from the cockpit while performing a wide-open throttle road
test. Cockpit or hood-mounted gauges are preferable. In order to obtain usable readings, the gauges should
measure pressure at the intake manifold and fuel rail. IF VEHICLE DOES NOT MAINTAIN PROPER FUEL
PRESSURE (50-65 PSI), DECREASE THROTTLE APPLICATION IMMEDIATELY. In some cases, extra vehicle
modifications can strain the stock fuel pump. If your vehicle has difficulty retaining adequate fuel pressure,
contact ATI ProCharger about the availability of an upgraded fuel system.
The engine on which the ProCharger®is to be installed should retain the factory compression ratio. If it
has been modified in any way, please consult ProCharger staff before proceeding with the installation. This
supercharger system is intended for use on STOCK, strong, well-maintained engines/transmissions. Installation
on a worn or troublesome powertrain should be reconsidered. ATI PROCHARGER WILL NOT BE HELD
RESPONSIBLE FOR DAMAGE TO A VEHICLE’S POWERTRAIN. ATI ProCharger is not responsible for ECM
tuning/programming on non-stock vehicles. ATI PROCHARGER recommends verifying that your vehicle has
current ECM updates from the vehicle manufacturer before installation.
For best performance and reliability, always use premium grade fuel (91 octane or higher) and listen closely
for signs of detonation, which might sound like ball bearings rolling around in a tin can. IF DETONATION
SHOULD OCCUR, OR IF YOU ARE UNSURE WHETHER WHAT YOU’RE HEARING IS DETONATION,
DECREASE THROTTLE APPLICATION IMMEDIATELY and please consult ATI ProCharger staff. Detonation
should not be an issue with a properly installed intercooled supercharger system, though OEM factory-shipped
engine and parts inconsistencies are possible on any vehicle.
