Pretty good but could be better

Opening the box, my first thought was that this looks like a high quality piece. I was disappointed that the instructions were essentially useless (although mostly unnecessary) and had to figure out how to make it fit a 2007 Envoy. An extra hole about 1" diameter has to be cut in the housing to connect the hose that was part of the original configuration. The throttle feels a little more responsive and there is a minimal increase in fuel mileage (.5 to 1 mpg depending on conditions).

This is my 3rd Volant system,(1999 gmc 1500 and 2003 gmc 1500hd 6.0) and this one disappoints. The performance is better but the molded cover fits poorly, not lining up and only 2 of the 3 retaining bolts will work. Would not recommend for this application.
