4.3 V6 Fuel Mileage
I have a 2007 NBS with the 4.3 V6 and I was wondering if anybody else was getting bad fuel mileage out of it? I'm averaging around 13-15 miles per gallon which is far below the advertised 21 miles to the gallon.

My 2000 Silverado used to get around 22 mpg, then after putting the fuel injector system in I was getting around 27, but now it's dropped severely to around 15. I freaked out naturally but it's only been about 2 years since I gave it a full and complete tune-up. It has 227,000 miles, still runs and pulls fantastic though.
