I bought a 2000 manual 4.0 with this doodad on it. Should I chuck it as I did with the CAI?

From their website...

Equip your vehicle with a Power Control Module (PCM) from Jet and release high-performance gains from your engine! Jet's dynamic spectrum tuning (DST) provides power gains across the entire power band, not just at full throttle. The Jet Performance Chips Power Control Module provides ignition advance, point-by-point air/fuel ratios, and gains of up to 25 horsepower. It also improves throttle response, acceleration, and your vehicles low-end torque

That, is the key to sub 10 second 1/4 mile times. You should take it to the track and hustle.

P.S. Make sure you launch in 4 Hi and kick it in to 2WD once you're moving. This will help keep those pesky front wheels on the ground.
 
I haven't seen a performance chip question about TJ's in years. I remember there used to be some questions about them 6+ years ago and the answer was they do nothing. That is a TJ relic right there.

Bolt on 4.0 performance. The fantasy that keeps us all awake at night.
