I put the before and after tire sizes in the tuner and this is what I'm reading...my tach seems spot on as the tuner and my truck are both reading 70mph on the freeway. I do about 60% driving on the freeway and 40% around town I'd say. Not at all driving agressively. Used to get 13.5mpg with my 2004 Ram 1500 HEMI quadcab short bed 2WD with 6in lift, 35in grapplers, K&N intake...what gives?
My buddy has a 2004.5 dually with 6in lift and 22.5 semi wheels on it and is getting 19mpg with bullydog tuner and got 22mpg before his mods and same numbers on the clock as I with 92,000.
I just picked this truck up so I'm going to go thru it with maintenance but I gotta say I'm a bit worried at how low it is....
pull MAP sensor and clean it, they are known to get dirty and cause a loss of mileage.
