Holley Rotary Boost Control

Adjustable boost control for Holley terminator ECU's. Harness plugs into the power tap connector from your Holley harness and requires you to make one connection to the input/output tap on the Holley harness. 

Go from 3 lbs. of boost to 20 lbs. with a simple turn of the knob. Dialing in your requested power level without the need to pack around a laptop. 

Simply mount the 12-position AEM switch in the location of your choosing with a 6-foot lead from the Holley harness and make the input connection. From there programming in the Holley can be done with the Holley dongle. This requires knowledge of Holley advanced tables and the input/output features.
