easy to install by polonerw, December 10, 2008

Ease of Use/Installation:
Overall Rating:

I was surprised how easy it was to install. I bought this to help my GMC Duramax get better fuel economy. Haven't seen a big change like some people say. I also added a Microchip program to help. I pull a 36 foot 5th wheel and did see some performance improvement there. It will take a while to recoup the cost in mileage savings. Still rather pleased with the purchase.
