For $175 or so, I bought a set of Precision fuel injectors at http://www.precisionautoinjectors.com/.
Install takes around 20 minutes, more or less, depending how much gunk you clean out of the injector rail.
I noticed right away that the Jeep starts faster, idles smoother. As for throttle response / power, I couldn't say. Maybe. I don't drive much & it had been a few weeks since I was in the Jeep anyway. Even then - I try to drive like grampa.
Between the injectors and the new TPS I saw a 3 mpg increase, up to 14.x mpg in short-trip city driving on 235's & a cold air intake.
The numbers, clearly, aren't that scientific. I did replace an out of spec TPS at the same time, and I may have a dragging brake caliper up front, etc.
Still, the engine definitely runs better with the better spray pattern of these new injectors. I would not be at all surprised if I picked up 1 mpg from these things alone.
