Hello from Alabama
I have a 2011 GMC Sierra 4x4 and I am interested in trying to mod my truck to see if I can get better mileage. I know...why did I buy this truck if I knew it sucks gas? Well, in 2011 gas wasnt over 3.00 a gallon. Besides I need a truck for various reasons. Looking forward to see how I can improve my mileage... Its a challange!
Cheers!
Tankman
