  • they probably didnt give you the torque numbers cause you smoked out their shop! lol. awesome truck! i'm running the spartan on mine too.

  • TOO MUCH FUEL!

  • Thats prolly the best sounding 6.4 ive ever heard.

  • these trucks are crazy fast dumbfucks. they can make the 600 hp no prob, especially with a 310 tune

  • You are the smartest person I know. David Dunbar is one of the best dyno operators in the country, which is the reason Scheid and TS Performance, and numerous others use him for their events. He gets a truck into 5th/6th gear where the converter is locked and the truck wont downshift. The reason the dyno in this video probably couldnt show torque is because it probably spiked the torque reading. I made the same power the "310 " test tune. This dyno is NOT accurate. But keep on thinking that

  • Wow man you are briliant, overdrive(old laymans term) or 5th gear on the 6.4 is when the torque convertor locks and that will give you your almost perfect 1:1 ratio. And that is not the proper way to dyno that truck.

  • Should have used a mustang dyno, dynojets can't put a load on the truck and are notorious for giving higher then actual numbers.

  • Dyno numbers are EASY to manipulate. Behind the seens you can mess with the weather settings, that can add/subtract 50-60hp. If you want more torque a simple change in the roller diameter can get you whatever number you want.

  • Its amazing how many people think there experts on youtube. A dyno does "filter" you can change the sample rate, which essentially takes an average of readings smoothing out the curve. You dont test in Overdrive either by the way. You want as close to 1:1 ratio as possible. 4th gear usually, unless its an allison.

  • Its quicker to calibrate a truck in one gear then get a tach signal from the crank.
