I did a stage 1 jet chip, 180 deg thermostat, headers, I run 93 and 31's. I had a new exhaust installed with new pipes and cats, only the muffler is stock. Inake is stock with a little homemade modification, it was pretty much as free flowing as you can get. Actually if you take out the curved inlet in the airbox, it's too wide open. The air filter gets dirty and can't filter everything so the butterfly on my throttle body gets stuck. Next are bigger injectors. In not saying it's fast but you'd be surprised for a wrangler with 100000 miles on it. The torque is the best part though especially since the TJ is under 3000 lbs.
Anyone else have a jet chip. Maybe the stage 2?
