Looking for Truck Tuner/Delete

Philadelphia PA

Description

Hello, I have a 2015 GMC Sierra 2500HD Pickup Truck it's Flex Fuel(I use regular gas). I drive a lot, and gas prices are killing me - I'm spending over $1200 a month on fuel, this is my daily driver. I need help with some kind of modification or installation of a tuner chip, or really anything that could help me increase my fuel economy. I'm not looking for any miracles, but even a 2-4 mpg increase would help me tremendously. Please friends, Thanks
