I just leveled my 05 1500 QC and put 35x12.5x20 Toyo mt's on it and I definetely need to change my gearing after this. Its a pain in the butt to drive on the highway because its constantly downshifting to try and keep speed up and its killing my gas. I shouldnt be whining about the gas though cause after all im the one that put 35s on it when gas prices are sooo damn high but I couldnt resist how good it looks.I dont know much about this and I wanted to get some suggestions on what to run. Oh and also I have yet to recalibrate my ecu for the larger wheels and tires and I was wondering what the best bang for the buck is out there as far as programmers go? Any help in either of these questions is very appreciated...Thanks in advance!

That being said, I would get the Superchips! It recalibrated my speedo to the T! it is dead on! Noticable gains in Torque and Power. I had the Hypertech and I hated it !!POS!!
4:56 Gears would be your best bet. I love mine! By far the best thing I have done to my truck yet!
