Fuel Mileage Difference

I installed my S&B CAI before any other mods to see what the difference would be. Bone stock I was getting 13.8 on the truck. Installed the CAI last night. Today I got 17.4. Even though this is the gauge on the truck giving me the numbers. Im sure sure it is accurate on just the diffence. Looking forward to see what the mini maxx and 5" dp back do.

I get right at 18 hwy with my set up. I'm getting 18.6 on the last 2 tanks since I got my 35 12.50s. If I'm in town and hwy mix I avg 15.5-16-5. I don't have a cai yet tho. When I still had my truck stock I might as well have poured my fuel in a ditch.

I wouldnt trust the guage in the truck, only way to tell for sure is hand calculating. My truck's MPG calculator is all over the place and ever right! on average it will read close to 4mpg's high, but not always.

Lie o meter is never right or a good way to tell. Heck driving from Austin to Dallas my dash ended at 32.5. I have the picture to prove it. Filled up in Austin and reset my gauges. Still haven't reset them. I should have filled up when I got home to see what I actually got but didn't have time. Still haven't but the LoM is reading 29 as of this morning (a little over half a tank gone).

Mines always dead on so long as it gets reset ever tank, but mines also stock.

How the hell are you guys getting 17 or 18 mpg. My 08 is stock and gets about 8.5 to 8.9 mpg. I would love just to get 13mpg.

I bought my truck about a month ago and have filled up 3 times. The truck guage told me respectivley 14.7, 15.3, and 11.2 (towing trailer). Hand calc told me 12.3, 12.5, and 9.8 (towing trailer).

Truck is stock fx4 cc. I bought an extended warrenty when I bought the truck so I still have 45k miles of warrenty. I dont want to risk void warrenty by doing a delete, but I would sure love to get 14-15 actual mpg.
