Just bought a 06 5.9. Installed brand new cp3. 6 brand new injectors and a fass 150. Truck runs great and has 285k miles. Want a chip for possibly better mpgs and power. Right now I'm getting around 16 with 5inch lift and 20x12 wheels with 35s. I guess I'm asking is a chip is too much with a truck with this type of mileage.
And what chips you guys running and mpgs power differences are you seeing. I was used to my ext cab ford having a lot more power down low then this.
EFI Live. 16 with 35's and the lift is doing pretty good already. But you could probably nudge that up with EFI. Any of the rest of the programmers are unlikely to gain you much if anything.
Thanks for input. I'm actually trying to lose the lift and put stock tires on it. Don't really mind the mileage for a 6k lb truck. Just hear people getting great numbers. I would like the extra power cuz down low is kind of sluggish
I put a edge on my truck and was getting 18 19 ish city and 22 highway I set the edge to tow and now i get around 22 23 city and 27 28 highway all day love it!
I got a bully dog gt for free from a buddy. Going to run that for a couple weeks see if I can get a mpg and I also put a bed cover
