600+ HP HEMI JEEP - Fuel Economy & Dyno Tune!

We swapped out the 392 Hemi for a 426 Hemi into our Jeep Wrangler JLU Rubicon! Making over 600 horsepower at the engine, a lot of viewers were wondering about not only the power it made at the wheel but also the fuel economy.

You would THINK that our miles per gallon would be terrible...right?!

Hope you all enjoy the video!
