Jeep JK Wrangler Unlimited Rubicon

JK is running a TeraFlex 2.5" Budget Boost lift,
295/75R17 (33") Toyo Open Country MT tires, and
an AEV Front Bumper.
The
interesting fact about this test is that
both Jeeps are essentially identical except for
the 4" difference in tire size. That fact
will show what larger tires will do for the
effective torque and horsepower. |

The Dynamometer - What and how we are
testing On
the OK Rubokon we are testing the results of the
installation of a Unichip performance module.
On the

have 3 baseline runs and 3 runs with each
performance product addition.
Each
test was a full throttle 3rd gear run from 2500
rpm to 5500 rpm with the engine running at
normal temperature.
 We
used regular octane pump gas and the shop
temperature was approx 55 degrees.
The dyno used in the
