2003 with the V10, want MPG advice
First off, NO HATERS. I knew this truck was a gas hog and I wanted him anyway. His name is Juggernaut. A V10 will never get the fuel mileage of a four cylinder, I know this full well. But I need a truck that can haul a 12,000 lb. trailer or more at a whim, and at a moments notice. My question to you fans out there is, what can I do to increase efficiency? Right now, the computer averages 9.3 MPG's. Again, I knew this going in, so NO FLAMERS. But, are there things I can do to help this? First on my list is a good reprogrammer, as mine was given the Death Flash. I have upgraded the exhaust already. Next is either an NV5600 or a G56 because the trans has 180,000 miles on it. So, friends of the last Big Block, what do you think?
