I have an 01 dodge with 6spd, 5 inch exhaust , fass150.i use to have a bully dog 3 stage chip with 0 30 60 hp settings.i ran it on 60 hp all the time and got great milage 20 in town.now I run my quad zillawith pulse but only get 17 mpg on max milage.any ideas why the decrease in mpgs?

 

Have you went on line and updated with the latest tune. I didn't get any better fuel milage compared to stock until I did that. But I did get a very old addrenaline that had been sitting on the shelf for a couple of years before it got sold to me.
