[QUOTE="Jassman, post: 1210951, member: 18674"] 3.55 and off the display..not hand calculated. I have hand calculated and it's within 2 tenths. I also have installed a Hypertech Speedo Calibrator cause at 70 I was doing 75..its correct with the GPS on my phone. Most of this has to do with how we all drive. I'm usually heavy on the foot, and when driving this way I see low 14's. I have been conscious that when I see a red light way ahead I get off the throttle, same thing on a off ramp. I accelerate evenly and have been using cruise. My truck only has 3000 miles so I know it will get better. Don't know if this helps..but sure sounds better.. I have a Absolute Performance 5" cold air intake and some cool duals from MBRP. [/QUOTE]
