RE: Bad Gas Mileage on a HEMI? LOL!!
flashpaq showed no noticeable gain in fuel economy in economy tune with 87 octane, and performance tune with 91 octane in my 04, city or highway. tested for about 2 months. Someone came up with this theory that maybe it only has MPG gains in hemi rams with MDS because the slight increase in torque can keep them in 4 cyl mode longer. just a thought
