When i did mine. its an 09 4x4 screw with 3:73 gears also. I drove a lot of highway and the lieometer read 20-22 mpg running 75mph.
Hand calculated was 2mpg less. Thats was with 5" flopro exhaust and running the 300 tune with my h&s tuner

I love my Spartan tuner. That being said I run the 300 el as a daily driver. Before I deleted I was seeing about 12 mpg mixed and maybe 13 high way. Post delete I'm seeing any where from 14.5 to 17 mixed driving, I'm hoping this will improve when we finally get summer blend fuel back. I recently made a 400 mile round trip to Kansas all hwy running 70 mph and hand calculated I got 22 mpg.

I run the H&S Mini Max on stock and get around 18mpg mostly highway miles. The mileage doesn't get better with added HP tunes, just the display says it does. Hand calculated my MPG is about 1.5 miles lower than the display mpg.

I have not replaced the air intake or the stock muffler. Just did the cat/dpf delete.

I have documented proof that contradicts that statement. Ran a year on the Spartan 300 averaged 16.5MPG (low was 15.3, high was 17.8). Ran Spartan 210 for last 3 months and haven't gotten over 15.5MPG on any tanks.

All hand calculated. Stock I was getting 13.5MPG hand calculated.

I don't know about Texas but around here using the last 3 months as an average doesn't count, winter mix fuels will cause lower milage, even with all other things the same.

I am lower on average than during the summer, yes, but even compared to last winter when I drove the 300, I'm significantly lower on the 210.

I have also talked to someone who did the delete and blown the head gasket any of y'all had that problem ?
And you have to have the programmer and delete pipe that's all right ?
