2009 Silverado 5.3L

Reviewed By Michael G (AMARILLO, TX) —12/14/2014 4:56 AM

I noticed an annoying exhaust note change when the AFM would kick in. The range device corrected that problem instantly. Product seems to well constructed of solid materials. I haven't had a chance to check any mileage changes but at this point I am satisfied to have the engine at full power. The truck is more responsive to the throttle.
