Too many variables.



Mixed driving does not show any real improvement. You need to as someone who drives a route with their truck...



I was getting from 12-19 mpg around town. I now drive my truck 65 miles one way to work and I get 24 MPG every tank...



I too am into statistics. I have an expel spreadsheet that has TONS of stats on my truck. The one thing I want to add is wind speed and average temperature to my stats. Your study has my interest piqued. I want to add that COMP box to see if it really helps!

I gained about 1 mile around town and about 2-2. 5 on highway

I drive the same route every day.

I have seen a 1 mpg increase with empty truck since I installed the EZ back in February. The EZ is the only mod except for gauges and removal of the factory muffler. The muffler was removed in November of 2002 with no mileage increase. Added the EZ and gained 1 mpg. Everything else is still stock. Seems to help mileage wise with loads a little, but I can't give you a specific amount... power is way better!

I gained about 1. 5 mpg unloaded- driving the same route every day. This is with the EZ on jumper 3. On jumper 1, I only gained about . 5 mpg. All figures are calculated by hand.

No change... . I get 15-16 mpg average before and after the EZ no matter how I drive it.

 

[Jim Ross]

Diablo Power Puck: about 1. 5 mpg increase on the hwy, maybe . 5mpg increase in the city.

 

[CAT 385]

No change on mine 15 to 16 mpg all the time



Buddys 02 gets 3 mpg better with ez, magnum flow, and 4" exhaust



buddys 01 gets 3 mpg better with ez, K&N.



They run the speed limit I don't usually and I also have injectors

 

[dshawhan]

TST on 4 = 1. 5-2. 0 increase no matter how I drive.

JVD on low = 2 mpg increase.

JVD on high = 1 mpg increase.

TST 0n 4 and JVD on high = 1 mpg decrease. (lots of smoke and power though)



All numbers are from unloaded conditions.



When loaded run TST on 4 with a 1 mpg increase.

JVD on low is same.
