Jet Performance Module Reviews


Excellent tuning module

Reviewed By Eric B (Aurora, CO) Reviewed for a 2006 Dodge Ram —6/16/2017 9:21 AM

The Jet Performance Stage 2 Module does what it says it does! You can hear the difference it makes in the spark and fuel timing curves. The power is noticable. I am using it with a cold air intake, high flow exhaust, and a TB spacer. The combination works as advertised.
