Because yj's didn't have as many electronically controlled aspects of the engine.

I have the same issue in my 02 with the six banger. I ended up having to drive ~170 miles in 4th gear (getting 10mpg the whole way!) due to those freak 40mph headwinds we had last week. Re-gearing will help but that's out of my range for now. New wires/plugs are on the immediate horizon and I'm sure they will also help slightly.

I posted asking if anyone recommended hypertechs, chips, or cold air intakes. The consensus was none of them work well in the jeeps. However, more people than not said a high performance throttle body spacer helps out. I haven't tried it yet, I think I am just going to get it STROKED...eventually.

What size engine do you have and what size tires are you running. And what is your axle ratio? You can find your axle ratio stamped into a small steel tag that is bolted onto the differential cover at its 9 o'clock position. It will have numbers like 3 07, 3 55, 3 73, 4 10, etc. stamped into it which indicates the axle's ratio.

Ummm the newer jeeps like TJ's that have the fuel injection throttle body, as stated in another thread TB spacers won't work!! There already specifically tuned. Ask Jerry he can explain alot more detailed. If your running a carb then they would work good but on a SFI it's not gonna do anything! I've also heard ppl that tried to use them complaining it actually made there jeeps run like crap on the SFI throttle body's!

hey, all I said is that I read mixed reviews, but more reviews were pro than con regarding TBs. I'm not recommending or speaking against them, b/c I haven't tried it.

Anyway you slice it, there's really only 3 surefire ways to get more umph outta a 6 banger: tune up, gear up, then stroke up. Or some combo of the three.

Just look at it this way....your throttle body regulates air comming in, not fuel and air like a carb does. The fuel is directly injected into each cylinder instead of being sucked down through the throttle body. By raising the tb up your initially doing nothing...not increasing the velocity, volume, or density.
