ok so i now have (2) 2010 dodge rams both with hemis and both 2wd crew cabs. But one has 3.21 gears and the other has 3.92 gears. i seen my shit ex step dad drive the truck with the 3.92 gears and at full throttle manual shift and with no rpm drop off. its like the engine barley droped a couple of hundread rpm. the dick head never gave me any info on how he did it. now i cant even shift like that with the truck with 3.92 gears or my truck with 3.21 gears. so what am i missing here???
