H&S tuner, 4" or 5" exhaust, and an AFE or S&B intake. Theres a ton of info here, do a search and you will have reading for days. Feel free to give us a call if you have any questions.
What are you basing your mpg off of? Did you get the speedo recalibrated or using a gps? I ask because if you changed tire size your odometer and speedo are off. I was showing some crazy numbers from the lie-o-meter in the dash but had no idea until I got my speedo working right.
The truck hasnt been calibrated or anything yet, so I know the numbers arent accurate. Just wanted an idea from all the experts on what I should be getting.
I asked because you said you lost almost 5mpg and that doesn't sound right. I lost about 2mpg going from my stockers to 37's on the factory 20's. Given my daily driving routine I'm getting about 13mpg. That's a 18 mile run from my house to base doing 60mph and the little bit of driving I do around town getting the kids from daycare and putting around base. My truck is stock.
