"Being somewhat of a sceptic and after quite a bit of research, I purchased and installed the Trail Jammer EXT. I amazed at the added power,throttle response and the ease of installation. I haven't had the opportunity to check fuel savings yet but, feel optimistic that it will be an improvement. Easy install." —Mike R from Madison, SD bought a Superchips Trail Jammer EXT Jeep Performance Package for a 2001 Jeep Wrangler, 4.0L 6-cyl. engine.
