I've had mechanical enhancement for years
www.creeperjeepers.org/davesrig.htm at least that's what my wife thinks. When I got my latest set of tires for this season (35x13.5x15 BFG Krawlers) she looked at it and said "well is your **** big enough yet" It's definitely GFMPH to get out and forget about
everything on the trails. In fact I was in Moab for a week 5 weeks after my surgery, spent the whole time not even thinking about
the future, PCa or anything but having fun.
With the new engine the JK got recently they're a pretty nice vehicle, we had an '07 4dr that was completely gutless even though it came with factory 4.10 gearing.
