Are you guys leaving your triple dog on extreme all the time? is there a differance in fuel mileage if you leave it on tow/ecomomy or extreme? just driving normal on mine on extreme it seemed to be like 10 oe 11 mpg around town

 

I drive around with mine on the Performance setting. Do not trust the computer reading for fuel mileage- Mine says 19 MPG, when I calculate it out, in reality it is only 16. That is with stock tires, driving carefully with a concious effort to go easy on the throttle. The bully dog did help with the mileage...It's up from about 13 MPG!

 

Extreme what's that??? Mine only stayed on Crazy Larry!!!!!

I"ve only got 4800 miles on my truck so its not broken in, but I think its doing good for rolling on 35" tires.

On tow/economy I have been getting (hand calc) 13.6-14.4 mpg
Performance: 15 mpg
Extreme: doing that setting on this tank, but got around 14.5 before on a partial tank.

 

ok then maybe i will just put it on performance or extreme if it dosnt make that much of a differnce i have 35's on it so the odo is off but i guess the whole thing is just trying to be easy on the throttle....when mine was stock is was like 12 or 13 at best

 

I've seen my best mileage on Crazy Larry.

 

I get my best milage on CL also and when I can keep it under 70 I get 21.3mpg on my normal driving during the week abd half hwy and half town. Yes this is hand calculated but I am not running 35" tires either.

 

best mileage using Crazy Larry or Scary Larry in my case. 20+mpg at 70mph

 

20.8 out of mine running Crazy Larry

 

Same, on average, on all levels as on stock. In fact, EVERY box that I have tried has gave little (0.5mpg max) or no fuel economy benefit.
