This PERFECT system includes a cam shaft custom ground specifically to get more torque and horsepower from your otherwise stock 4.0L engine. As tested on our Digalog engine dyno, with this cam and the PERFECT engine management system on your 4.0L engine expect to gain 20 horsepower and 10 lb/ft torque. It also allowed for 19mpg in a 1989 Jeep Wrangler with 31-10.50 tires and a three speed automatic. At 70mph it was taching at 2800rpms and not missing a beat. Wait til you step on the loud pedal with this one in your ride.
